DETAILED DESCRIPTION

[0040] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0041] It should be noted that when an element is referred to as being "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

[0042] It should be understood that the orientation or position relationship indicated by terms such as "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0043] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0044] The functional and appearance integrated testing equipment provided by the embodiment of the present invention is now described. The functional and appearance integrated testing equipment can perform functional testing and appearance testing on products such as chips.

[0045] In one embodiment of the present invention, see Figure 1The integrated function and appearance testing equipment includes a tray feeding mechanism 1, a function testing mechanism 2, a test grabbing mechanism 3, an appearance testing mechanism 4, a good product discharging mechanism 5, a replenishing material grabbing mechanism 6, a replenishing material transmission mechanism 7 and a defective product placement mechanism 8. The transmission direction of the tray feeding mechanism 1 is set along the Y axis. The tray feeding mechanism 1 is used to transport the tray loaded with the product to be tested, and can move the tray loaded with the product to be tested to a position where the test grabbing mechanism 3 can grab it. The function testing mechanism 2 is used to perform functional tests on the product, such as electrical tests, high-voltage tests, etc., and its test items are not limited here. The test grabbing mechanism 3 can grab the product from the tray on the tray feeding mechanism 1 and move it to the function testing mechanism 2, so that the function testing mechanism 2 can perform functional tests on the product. The appearance testing mechanism 4 is used to confirm the number of products, check the appearance and placement direction of the products. The transmission direction of the good product discharging mechanism 5 is set along the Y axis, and is used to transport the tray loaded with good products. The feeding grabbing mechanism 6 is used to move the products with poor appearance and wrong placement direction in the good product discharging mechanism 5 to the bad product placement mechanism 8, and load good products. The feeding transmission mechanism 7 provides good products for the feeding grabbing mechanism 6, and the bad product placement mechanism 8 is used to place bad products. Specifically, when the function and appearance integrated testing equipment is working, the product to be tested is placed on the material tray and transmitted by the material tray feeding mechanism 1. When it is transmitted to the predetermined position, the test grabbing mechanism 3 grabs the product from the material tray feeding mechanism 1 and transfers the product to the functional testing mechanism 2. The functional testing mechanism 2 performs a functional test on the product. The products that pass the functional test are moved by the test grabbing mechanism 3 to the material tray of the good product discharging mechanism 5, and the products that fail the functional test are moved by the test grabbing mechanism 3 to the bad product placement mechanism 8. The good product discharging mechanism 5 drives the material tray on it to continue moving along the Y-axis direction to the appearance inspection mechanism. The appearance testing mechanism 4 counts and inspects the appearance of the products on the material tray. If there is a shortage of material on the material tray, the replenishment grabbing mechanism 6 grabs the good products from the replenishment transmission mechanism 7 and fills them into the shortage position. If the product on the material tray has appearance defects or is placed in the wrong direction, the replenishment grabbing mechanism 6 first grabs the product with appearance defects or wrong placement direction to the defective product placement mechanism 8, and then grabs the good products from the replenishment transmission mechanism 7 and fills them into the shortage position, so that the good products that have passed the appearance test and the functional test fill the material tray on the good product discharging mechanism 5, and the good product discharging mechanism 5 moves the material out. In this way, the function and appearance integrated testing equipment can perform both functional and appearance tests on the product, simplify the testing process, and do not need to manually carry the material tray between the two devices, thereby improving the testing efficiency and reducing manpower investment.

[0046] In one embodiment of the present invention, see Figure 1, the tray feeding mechanism 1, the function testing mechanism 2, the good product discharging mechanism 5, and the bad product placement mechanism 8 are arranged in sequence along the X-axis direction, so that the product also gradually moves along this direction. Since the transmission directions of the tray feeding mechanism 1 and the good product discharging mechanism 5 are both set along the Y-axis, when the tray feeding mechanism 1, the function testing mechanism 2, the good product discharging mechanism 5, and the bad product placement mechanism 8 are arranged in sequence along the X-axis direction, the space in the X-axis direction can be fully utilized, and the layout can be reasonably arranged to reduce the space occupied by the function and appearance integrated test equipment.

[0047] Optionally, the transmission direction of the feeding transmission mechanism 7 is also set along the Y axis, so that the feeding tray can move along the Y axis, and the feeding grabbing mechanism 6 can move along the X axis, so as to cooperate with the moving direction of the feeding tray and grab the good products at any position on the feeding tray. In this way, the third X axis moving module 61 of the feeding grabbing mechanism 6 and the first X axis moving module 31 and the second X axis moving module 32 on the test grabbing mechanism 3 are arranged in parallel and can be fixed on the same working bracket 92, which is more convenient for layout to save space.

[0048] In one embodiment of the present invention, see Figure 2 The tray feeding mechanism 1 includes a tray stratification mechanism 11, a tray moving mechanism 12 and a tray stacking mechanism 13. The tray stratification mechanism 11 is used to separate the bottom tray in the stacked trays to the tray moving mechanism 12, without the need for manual separation of the trays, which can improve the degree of automation of the tray transmission device. Specifically, the tray stratification mechanism 11 includes a first lifting component 111 and a first supporting component 112. The stacked trays are placed on the first lifting component 111. The first lifting component 111 can drive the stacked trays to move up and down. The first supporting component 112 is used to support the other trays except the bottom tray, so that the bottom tray can be separated from the other trays. When the bottom tray needs to be separated, the first lifting assembly 111 raises or lowers the stacked trays to a predetermined height, and the first supporting assembly 112 supports the other trays except the bottom tray, so that only one tray is left on the first lifting assembly 111. The first lifting assembly 111 descends and drops the tray onto the supporting tray 122 of the tray moving mechanism 12, thereby separating the bottom tray from the other trays. Figure 3 The tray moving mechanism 12 transports the trays separated by the tray stratification mechanism 11 to the testing station for the testing mechanism to take the materials, and then transports the empty trays to the tray stacking mechanism 13 for stacking.

[0049] In other embodiments, the material tray feeding mechanism 1 may also only include the material tray moving mechanism 12 .

[0050] Optionally, the tray moving mechanism 12 includes a transmission drive 121, a carrier tray 122, a clamping assembly 123 and a guide rail structure 124. The carrier tray 122 is used to place the tray, and the carrier tray 122 is connected to the moving end of the transmission drive 121. The transmission drive 121 drives the carrier tray 122 to move between the tray layering mechanism 11 and the tray stacking mechanism 13, so that the tray can be transported. When the tray is placed on the carrier tray 122, the clamping assembly 123 can clamp the tray to prevent the tray from tipping over from the carrier tray 122. The guide rail structure 124 is used to guide the tray to make the transportation of the tray smoother. The tray stacking mechanism 13 is used to stack empty trays without manual stacking, which can improve the automation of the tray transmission device. Specifically, the tray stacking mechanism 13 includes a second supporting assembly 132 and a second lifting assembly 131. The second supporting assembly 132 is used to support the already stacked trays, and the second lifting assembly 131 is used to push the transferred trays to the bottom layer of the already stacked trays. Specifically, the second supporting assembly 132 pushes the already stacked trays to a predetermined position, so that the bottom of the already stacked trays is vacant, the tray moving mechanism 12 transfers the vacant trays to the tray stacking mechanism 13 (below the already stacked trays), the second lifting assembly 131 rises, and pushes the vacant trays to the bottom of the already stacked trays, the second supporting assembly 132 releases the trays, the second lifting assembly 131 continues to rise to the height of a tray, and the second supporting assembly 132 supports the trays again, so that the vacant trays can be stacked in sequence.

[0051] In one embodiment of the present invention, see Figure 3, the first lifting assembly 111 includes a lifting motor 1111, a pulley assembly 1112, a lifting screw 1113 and a first lifting bracket 1114. The lifting motor 1111 can be a servo motor, which outputs a rotational motion. One of the pulleys of the pulley assembly 1112 is fixed to the output end of the lifting motor 1111, and the other pulley of the pulley assembly 1112 is fixedly connected to the lifting screw 1113. The first lifting bracket 1114 is threadedly connected to the lifting screw 1113, and the guide column is used to guide the movement of the first lifting bracket 1114. When the lifting motor 1111 is working, the lifting screw 1113 can rotate accordingly. When the lifting screw 1113 rotates, the first lifting bracket 1114 moves up and down under the guidance of the guide column. When the tray is placed on the first lifting bracket 1114, it can move up and down with the first lifting bracket 1114. Among them, the movement of the output end of the lifting motor 1111 can be controlled more accurately than that of the cylinder, and the cooperation between the lifting cylinder 1311 and the lifting screw 1113 can further improve the displacement accuracy of the first lifting bracket 1114, prevent the stacking tray from being lifted or lowered, and ensure that the first supporting assembly 112 can be accurately clamped on the side of the stacking tray. The setting of the pulley assembly 1112 allows the lifting screw 1113 and the lifting motor 1111 to be set on different axes, which facilitates the layout of the first lifting assembly 111. In other embodiments, the pulley assembly 1112 in the first lifting assembly 111 can also be replaced by a sprocket assembly, a gear assembly, or other structures.

[0052] Optionally, see Figure 3 The first lifting assembly 111 further includes a lifting installation plate 1115, and the lifting motor 1111 and the pulley assembly 1112 are both installed on the lifting installation plate 1115. More specifically, the lifting motor 1111 is fixed to the top surface of the lifting installation plate 1115, and the pulley assembly 1112 is fixed to the bottom surface of the lifting installation plate 115, so that the height space used by the lifting motor 1111 can overlap with the height space used by the lifting screw 113, which will not increase the volume of the first lifting assembly 111, and can make the structure of the first lifting assembly 111 more compact.

[0053] Optionally, see Figure 2 and Figure 3 The first lifting assembly 111 further includes a first support column 1116, one end of which is fixed to the lifting installation plate 1115, and the other end of the first support column 1116 is fixed to the guide rail structure 124, so that the lifting installation plate 1115 can be stably installed on the guide rail structure 124. The number and distribution of the first support columns 1116 are not limited here. The number of the first support columns 1116 can be selected as four, which are supported between the guide rail structure 124 and the lifting installation plate 1115.

[0054] Optionally, see Figure 2and Figure 3 , the first lifting bracket 1114 is slidably connected to the guide rail structure 124, so that the movement of the first lifting bracket 1114 is smoother. More specifically, the first lifting bracket 1114 includes a first lifting bottom plate 11141, a second support column 11142 and a first push-up plate 11143. The first lifting bottom plate 11141 is threadedly connected to the lifting screw 1113, and the two ends of the second support column 11142 are respectively fixedly connected to the first push-up plate 11143 and the second lifting bottom plate 13121, and the second support column 11142 is slidably connected to the guide rail structure 124. The first push-up plate 11143 is used to push and support the material tray. Optionally, the number of the first push-up plates 11143 is two. When the carrier plate 122 moves to the top of the first lifting assembly 111, the two first push-up plates 11143 are respectively located on both sides of the carrier plate 122 to avoid interference with the carrier plate 122. At least one second support column 11142 is fixed to each first push-up plate 11143 , and two or more second support columns 11142 may also be fixed to each first push-up plate 11143 .

[0055] In one embodiment of the present invention, see Figure 4 , the first supporting assembly 112 includes at least four first telescopic cylinders 1121, and at least two first telescopic cylinders 1121 are respectively provided on opposite sides of the stacked material tray. When the first supporting assembly 112 includes four first telescopic cylinders 1121, two of the first telescopic cylinders 1121 are provided on one side of the stacked material tray, and the other two first telescopic cylinders 1121 are provided on the other side of the stacked material tray, so that at least two first telescopic cylinders 1121 are provided on the clamped side of the stacked material tray to ensure the stability of the clamped material tray. Optionally, when it is necessary to separate the bottommost material tray, the first telescopic cylinder 1121 extends a locking tongue, so that the locking tongue is inserted between the bottommost material tray and the penultimate material tray, so that the bottommost material tray can be separated from the stacked material tray. Alternatively, when it is necessary to separate the bottommost material tray, the first telescopic cylinder 1121 extends a push rod, and the push rod is extended to abut against the side wall of the penultimate material tray, so that the bottommost material tray can also be separated from the stacked material tray.

[0056] Optionally, the first telescopic cylinder 1121 may be fixed on the guide rail body 1242 of the guide rail structure 124 .

[0057] Optionally, see Figure 4The tray layering mechanism 11 also includes a first positioning structure 113, which is used to position the stacked trays stacked above the first lifting assembly 111. The first positioning structure 113 includes four first positioning columns 1131, and the cross-section of the first positioning column 1131 is L-shaped, or the cross-section of the first positioning column 1131 has an L-shaped recess. The four first positioning columns 1131 can form a frame-shaped space to limit the four corners of the tray. The first positioning column 1131 can be fixed on the guide rail structure 124. A first height sensor 1132 is provided on at least one first positioning column 1131, which is used to detect the number of stacked trays above the first lifting assembly 111. When the number of trays reaches the set minimum value, an alarm can be sounded to prompt the staff to put in a new tray.

[0058] In one embodiment of the present invention, see Figure 4 In the tray moving mechanism 12, the guide rail structure 124 includes a track seat 1241 and two guide rail bodies 1242. The two guide rail bodies 1242 are arranged at intervals to form a channel for the tray to pass through. When the tray is transported, the opposite sides of the tray are placed on the two guide rail bodies 1242 respectively. More specifically, the guide rail body 1242 has a positioning step, the edge of the tray is placed on the top surface of the positioning step, and the side of the tray abuts against the side of the positioning step, so that the tray is guided and the tray is more stable during movement.

[0059] Optionally, the first telescopic cylinder 1121 is fixed to the guide rail body 1242. When the number of the first telescopic cylinders 1121 of the first supporting assembly 112 is four, two of the first telescopic cylinders 1121 are fixed to one of the guide rail bodies 1242, and the other two of the first telescopic cylinders 1121 are fixed to the other guide rail body 1242. The first positioning structure 113 is fixed to the guide rail body 1242. When the number of the first positioning columns 1131 is four, two of the first positioning columns 1131 are fixed to one of the guide rail bodies 1242, and the other two of the first positioning columns 1131 are fixed to the other guide rail body 1242. Optionally, one end of the first support column 1116 is fixed to the track seat 1241, and the second support column 11142 is slidably connected to the track seat 1241.

[0060] Optionally, see Figure 4The transmission drive member 121 includes a transmission motor 1211, a transmission screw rod 1212 and a transmission nut seat 1213. The transmission screw rod 1212 is fixed to the output shaft of the transmission motor 1211. The transmission screw rod 1212 can be fixedly connected to the output shaft through a coupling. The transmission nut seat 1213 is threadedly connected to the transmission screw rod 1212, and the carrier plate 122 is fixed on the transmission nut seat 1213. When the transmission motor 1211 is working, it outputs a rotational motion to rotate the transmission screw rod 1212. When the transmission screw rod 1212 rotates, the transmission nut seat 1213 and the carrier plate 122 move axially along the transmission screw rod 1212, so that the carrier plate 122 moves between the material tray layering mechanism 11 and the material tray stacking mechanism 13. The transmission of the material tray through the transmission screw rod 1212 can make the material tray displacement accuracy higher. The transmission motor 1211 and the transmission screw rod 1212 can be installed on the track seat 1241.

[0061] In one embodiment of the present invention, the number of clamping assemblies 123 is two, and the two clamping assemblies 123 are respectively arranged on both sides of the carrier plate 122, and are used to clamp the opposite sides of the material tray to prevent the material tray from tipping over. The number of clamping assemblies 123 can also be greater than two, and the clamping assemblies 123 can be arranged on both opposite sides of the carrier plate 122. In other embodiments of the present invention, please refer to Figure 5 One side of the carrier plate 122 is bent to form a baffle plate 1221, and the other side of the carrier plate 122 is provided with a clamping assembly 123, and the number of the clamping assemblies 123 on this side is not limited here.

When the hook claw cylinder 1231 is in motion, the hook claw body 1232 can slide relative to the hook claw cylinder 1231 in the length direction of the strip hole 123210, thereby preventing the hook claw body 1232 from being stuck at the output end of the hook claw cylinder 1231. The cross-sectional diameter of the part where the output end of the hook claw cylinder 1231 passes through the hook claw body 1232 is greater than the width of the bar hole 123210. The cross-sectional diameter of the output end of the hook claw cylinder 1231 at the annular groove 12310 is smaller than the width of the bar hole 123210, so that the hook claw body 1232 can be clamped on the output end of the hook claw cylinder 1231.

Among them, the material grabbing slider 3327 can be fixed on the vertical portion 33222 of the connecting frame 3322. Each nozzle assembly 332 is correspondingly provided with a material grabbing slide rail 3326 and a material grabbing slider 3327, or all nozzle assemblies 332 share the material grabbing slide rail 3326 and the material grabbing slider 3327.
