[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0034] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0035] For ease of description, spatial relative terms may be used herein to describe the relative positional relationship or movement of one element or feature relative to another element or feature as shown in the figure, such as "inside", "outside", "inner side", "outer side", "below", "below", "above", "above", "front", "back", etc. Such spatial relative terms are intended to include different orientations of the device in use or operation in addition to the orientation depicted in the figure. For example, if the device in the figure undergoes a position flip or a posture change or a motion state change, then these directional indications also change accordingly, for example: an element described as "below other elements or features" or "below other elements or features" will subsequently be oriented as "above other elements or features" or "above other elements or features". Therefore, the example term "below..." may include both upper and lower orientations. The device may be otherwise oriented (rotated 90 degrees or in other directions) and the spatial relative descriptors used herein are interpreted accordingly.

[0036] In order to solve the technical problem that the existing manual suction of products leads to low placement accuracy and affects the testing efficiency of products, the present application provides a vacuum suction device and equipment, which can improve the suction accuracy and placement accuracy, ensure the accuracy of functional testing of subsequent module products, and improve testing efficiency.

[0037] Figure 2-Figure 4 A vacuum suction device 1 provided in an embodiment of the present application includes a sleeve 11, a sliding member 12, a suction nozzle 13 and an elastic sheet 14. The sleeve 11 is provided with a through first cavity 111 along its own length direction; one end of the sliding member 12 is slidably arranged in the first cavity 111 of the sleeve 11; the suction nozzle 13 is arranged at the end of the sliding member 12 away from the sleeve 11, and is used to adsorb the module product 3; the elastic sheet 14 has a first end 1401 and a second end 1402, the first end 1401 of the elastic sheet 14 is connected to the sleeve 11, and the second end 1402 of the elastic sheet 14 is connected to the sliding member 12, so as to buffer the reaction force generated when the suction nozzle 13 adsorbs the module product 3.

[0038] It can be understood that the end of the sleeve 11 away from the suction nozzle 13 can be connected to the air inlet end of the external existing equipment air system, the sliding member 12 can move up and down in the first cavity 111 of the sleeve 11, and the suction nozzle 13 is connected to the bottom of the sliding member 12. In actual operation, the air is sucked by the equipment air system to evacuate the internal air of the sleeve 11, the sliding member 12 and the suction nozzle 13, and then the module product 3 is positioned and sucked by the suction nozzle 13. The first end 1401 of the elastic sheet 14 is connected to the sleeve 11, and the second end 1402 of the elastic sheet 14 is connected to the sliding member 12, which can limit the rotation of the sliding member 12 relative to the sleeve 11 to ensure the placement accuracy of the module product 3 on the test fixture 5. Specifically, after the equipment receives the work instruction, the transfer device equipped with the vacuum suction device 1 will move to the top of the tray 4 where the module product 3 is placed (the first designated position), and the suction nozzle 13 is aligned with the module product 3, such as Figure 5 As shown. After the position is determined correctly, the transfer device will move vertically downward until the end of the suction nozzle 13 away from the sliding member 12 contacts the module product 3. After contact, the vacuum solenoid valve of the device sends a vacuum suction command, and the air circuit system of the device can be used to evacuate the air in the sleeve 11, the sliding member 12 and the suction nozzle 13. After the air is evacuated, the module product 3 is positioned and sucked through the suction nozzle 13, as shown in FIG. Figure 6 Then the transfer device moves to the top of the test fixture 5 (the second designated position). After the position is confirmed, the transfer device moves vertically downward. When it moves to the set height, the vacuum solenoid valve of the device sends a vacuum blowing instruction to place the module product 3 at the designated position of the test fixture 5. Figure 7 Compared with the existing method of manually sucking and placing the module product 3, the embodiment of the present application can improve the suction accuracy and placement accuracy, ensure the accuracy of the functional test of the subsequent module product 3, and improve the test efficiency.

[0039] Optionally, the elastic sheet 14 in the embodiment of the present application is made of a spring steel material with a thickness of 0.5 mm (its thickness can also be adjusted according to actual production needs) to form a retaining spring, which can be deformed under a force of more than 0.5N. When the suction nozzle 13 adsorbs the product 3, the elastic deformation of the elastic sheet 14 can buffer the reaction force generated when the product 3 is adsorbed, and can also make up for the horizontal height difference between the product 3 and the tray 4 or the test fixture 5. When it is necessary to adsorb multiple products 3, multiple vacuum suction devices 1 can be set on the transfer device of the vacuum suction equipment, and the elastic sheet 14 can make up for the horizontal height difference of multiple products 3.

[0040] It should be noted that the connection between the first end 1401 of the elastic sheet 14 and the sleeve 11, and between the second end 1402 of the elastic sheet 14 and the sliding member 12 can be a fixed connection or a snap-on connection, which can achieve the purpose of limiting the rotation of the sliding member 12 relative to the sleeve 11, and is not limited here.

[0041] like Figure 1 As shown, in the existing vacuum suction device 2, a spring-designed buffer structure is adopted. The existing vacuum suction device 2 includes a base 21, a slide bar 22 and a suction head 23. The slide bar 22 is slidably connected to the base 23. A spring 24 is sleeved on the peripheral side of the slide bar 22. A positioning pin 25 is provided on the base to limit the rotation of the slide bar 22. Compared with the existing device, the vacuum suction device 1 provided in the embodiment of the present application connects the sliding member 12 and the sleeve 11 by using an elastic sheet 14, and there is no need to set a positioning pin. The sliding member 12 can be directly limited to prevent the sliding member 12 from horizontal displacement or axial rotation relative to the sleeve 11, thereby saving manufacturing costs. Since the spring 24 in the existing device is wrapped around the peripheral side of the slide bar 22, it is also inconvenient to clean the peripheral side of the slide bar 22. However, the elastic sheet 14 is adopted in the present application, which makes disassembly and cleaning more convenient.

[0042] like Figure 8 As shown, the elastic sheet 14 includes a pair of elastic plates 141 disposed oppositely and a pair of connecting plates 142 disposed oppositely, the elastic plates 141 and the connecting plates 142 are connected in sequence, and the two connecting plates 142 are respectively connected to the sleeve 11 and the sliding member 12. The connecting plates 142 can limit the rotation of the sliding member 12 relative to the sleeve 11 to ensure the placement accuracy of the module product 3 on the test fixture 5.

[0043] The end of the sleeve 11 close to the nozzle 13 is provided with a first shoulder 112, and a first limiting groove 1121 is provided on the first shoulder 112. A first clamping groove 1421 matching the circumference of the first limiting groove 1121 is provided on the connecting plate 142 located at the first end 1401 of the elastic sheet 14, and the first clamping groove 1421 is clamped and connected with the first shoulder 112. The connecting plate 142 is clamped on the first shoulder 112 of the sleeve 11, and the first clamping groove 1421 and the first shoulder 112 can be set to be interference fit, so that relative displacement cannot occur between the elastic sheet 14 and the sleeve 11.

[0044] The end of the sliding member 12 away from the sleeve 11 is provided with a second shoulder 121, and a second limiting groove 1211 is provided on the second shoulder 121. A second clamping groove 1422 matching the circumference of the second limiting groove 1211 is provided on the connecting plate 142 located at the second end 1402 of the elastic sheet 14, and the second clamping groove 1422 is clamped and connected with the second shoulder 121. The connecting plate 142 is clamped on the second shoulder 121 of the sliding member 12, and the second clamping groove 1422 and the second shoulder 121 can be set to be interference fit, so that relative displacement cannot occur between the elastic sheet 14 and the sliding member 12, so as to prevent the sliding member 12 from rotating relative to the sleeve 11 and affecting the subsequent placement accuracy of the product 3.

[0045] Furthermore, if Fig. 9 and Fig.10 As shown, the first clamping slot 1421 has a first opening 1423, and the size t1 of the first opening 1423 is smaller than the diameter D1 of the first limiting slot 1121; the second clamping slot 1422 has a second opening 1424, and the size t2 of the second opening 1424 is smaller than the diameter D2 of the second limiting slot 1211; optionally, the two connecting plates 142 are parallel to each other, and the first opening 1423 and the second opening 1424 are oriented in the same direction, so that the elastic sheet 14 can be assembled on the sleeve 11 and the sliding member 12. When the elastic sheet 14 needs to be installed, the first opening 1423 of the elastic sheet 14 is aligned with the first limiting slot 1121 of the sleeve 11, and the second opening 1424 of the elastic sheet 14 is aligned with the second limiting slot 1211 of the sliding member 12, and the elastic sheet 14 is slightly pushed with force, so that the two ends of the first clamping slot 1421 or the two ends of the second clamping slot 1422 are slightly tilted, and the installation of the elastic sheet 14 can be achieved.

[0046] In some embodiments, Figure 6 As shown, the middle portion of the elastic plate 141 is bent away from the sliding member 12 so that the cross section of the elastic plate 141 is "V"-shaped. The elastic plate 141 can change its bending angle after being subjected to force and return to a free state under the action of the elastic restoring force, thereby achieving buffering.

[0047] The sleeve 11 is placed vertically, that is, the length direction of the sleeve 11 is parallel to the vertical direction, the elastic sheet 14 is in a free state (not sucking the product 3), the bending angle θ1 of the elastic plate 141 is 80°-85°, and the distance h1 between the end of the sleeve 11 close to the suction nozzle 13 and the end of the sliding member 12 away from the suction nozzle 13 is 9.5mm-10.5mm. Figure 5As shown; the elastic sheet 14 is in the working state (the elastic sheet 14 is squeezed by the sleeve 11). In order to ensure the stability of sucking the product 3, the sleeve 11 may squeeze the elastic sheet 14 when sucking the product 3. When the squeezing force reaches more than 0.5N, the bending angle θ2 of the elastic plate 141 is 40°-85°. When the elastic sheet 14 reaches the maximum deformation, the distance h2 between the end of the sleeve 11 close to the suction nozzle 13 and the end of the sliding member 12 away from the suction nozzle 13 is 4.5mm-5.5mm. Figure 6 shown.

[0048] like Figure 2 and Figure 4 As shown, the sliding member 12 is provided with a second cavity 122 connected to the first cavity 111 along its own length direction, and the suction nozzle 13 is provided with a suction hole 131 connected to the second cavity 122. After the air circuit system of the equipment is evacuated to evacuate the air inside the sleeve 11, the sliding member 12 and the suction nozzle 13, the first cavity 111, the second cavity 122 and the suction hole 131 form a negative pressure channel to adsorb the module product 3. A plurality of suction holes 131 may be provided, and the plurality of suction holes 131 are evenly distributed on the side of the suction nozzle 13 away from the sliding member 12 to improve the uniformity of the suction force of the suction nozzle 13.

[0049] In an optional embodiment, the sliding member 12 and the suction nozzle 13 are fixedly connected, and the connection between the two can be sealed with a sealant. It can be understood that the assembly process of the vacuum suction device 1 provided in this embodiment is as follows: first, the sleeve 11 is sleeved on the sliding member 12, and the sliding member 12 is slid along its own length direction in the direction close to the first shoulder 112 of the sleeve 11, until the distance between the first limit groove 1121 and the second limit groove 1211 is 10mm and stops sliding; then, the first end 1401 of the elastic sheet 14 is connected to the first shoulder 112 of the sleeve 11, and the second end 1402 of the elastic sheet 14 is connected to the second shoulder 121 of the sleeve 11; finally, the sealant is applied to the connection area between the sliding member 12 and the suction nozzle 13, and the suction nozzle 13 is fixedly set on the sliding member 12, and the assembly is completed.

[0050] In an optional embodiment, if Fig.11As shown, a clamping column 123 is provided at one end of the sliding member 12 facing the suction nozzle 13, and a third clamping groove 132 is provided on the suction nozzle 13 to be clamped and connected with the clamping column 123, and the third clamping groove 132 is connected with the suction hole 131. A clamping block 124 is provided at one end of the clamping column 123 close to the suction nozzle 13, and the circumference of the end of the third clamping groove 132 away from the sliding member 12 is larger than the circumference of the other end, so that an interference fit is formed between the clamping block 124 and the third clamping groove 132 to limit the displacement of the clamping block 124 relative to the suction nozzle 13. Optionally, a guide slope is provided on the side of the clamping block 124 away from the second cavity 122, and the guide slope plays a guiding role in the clamping connection process between the clamping column 123 and the third clamping groove 132. It can be understood that the assembly process of the vacuum suction device 1 provided in this embodiment is different from that of the above-mentioned embodiment in that the slot of the suction nozzle 13 is sleeved on the clamping column 123 of the sliding member 12, and pressed hard so that the clamping column 123 of the suction nozzle 13 is clamped and connected to the third slot 132 of the suction nozzle 13.

[0051] The embodiment of the present application also provides a vacuum suction device, including a transfer device and the vacuum suction device 1 as described above, the transfer device is used to transfer the module product 3 from a first designated position (such as a tray 4) to a second designated position (such as a test fixture 5); the sleeve 11 of the vacuum suction device 1 is arranged on the transfer device. The working principle of the vacuum suction device is referred to the above embodiment of the vacuum suction device 1, and will not be repeated here.

[0052] It should be noted that the transfer device can adopt a robotic arm in the prior art to absorb the module product 3 and then accurately transfer the module product 3 to the test fixture 5, thereby further improving the placement accuracy on the test fixture 5 and improving the test efficiency.

[0053] There may be multiple vacuum suction devices, which are arranged in an array on the transfer device to adapt to the automated self-collection test operation of multiple or multiple module products and improve the operation efficiency. Those skilled in the art may adjust the number of vacuum suction devices according to actual needs, or adjust the horizontal spacing between the suction nozzles of two adjacent vacuum suction devices, or adjust the vertical spacing between the suction nozzles of two adjacent vacuum suction devices.
