[0033] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0034] See also Figure 1-Figure 15 As shown, this embodiment provides a memory stick assembly device, which includes: a material clamping and pressing device 10, a transport robot 20 and a detection and correction device 30.

[0035] The transport robot 20 is used to transport the material clamping and pressing device 10 to the material taking station A, the inspection and correction station B, and the assembly station C.

[0036] In this embodiment, a material storage tray 101 is provided at the material taking station A, and a memory stick 100 is stored in the material storage tray 101. A memory stick slot 200 is provided at the assembly station C, and the memory stick slot 200 is provided on the server motherboard.

[0037] The material clamping and pressing device 10 includes: a material clamping mechanism 11 and a material pressing mechanism 12. The material clamping mechanism 11 is used to clamp a plurality of memory sticks 100 at the material taking station A, or release the clamped memory sticks 100 to the detection and correction station B or clamp the memory sticks 100 from the detection and correction station B, or release the memory sticks 100 to the memory stick slot 200 of the assembly station C. The material pressing mechanism 12 is used to press-fit each memory stick 100 into the memory stick slot 200 in sequence at the assembly station C. The method of press-fitting the memory sticks 100 into the memory stick slot 200 in sequence can not only ensure that the force on each memory stick 100 is uniform during the press-fitting process, but also ensure that sufficient pressing force is provided, and at the same time, the pressing force can be dispersed at different time points, thereby reducing the force on the mainboard and avoiding the simultaneous press-fitting of multiple memory sticks 100, which may cause the mainboard to rupture due to excessive force.

[0038] The detection and correction device 30 includes: a front and back detection mechanism 31 and a front and back correction mechanism 32. The front and back detection mechanism 31 is used to detect whether each memory stick 100 located at the detection and correction station B is installed upside down, and the front and back correction mechanism 32 is used to lift the memory stick 100 installed upside down to the top of other memory sticks 100 and swap the front and back of the memory stick 100, so as to correct the memory stick 100 installed upside down. Among them, the other memory sticks 100 are memory sticks 100 whose front and back are not installed upside down relative to the memory stick 100 installed upside down. In a preferred embodiment, after the memory stick 100 installed upside down is lifted to the top of other memory sticks 100, the front and back of the memory stick 100 are swapped by rotating it 180° in a plane.

[0039] In this embodiment, the transport robot 20 transports the material clamping and pressing device 10 to the material picking station A, and the material clamping mechanism 11 clamps multiple memory sticks 100 from the material storage tray 101 of the material picking station A. After clamping, the transport robot 20 transports the material clamping and pressing device 10 to the inspection and correction station B, and the material clamping mechanism 11 releases the clamped memory sticks 100 to the inspection and correction station B. The inspection and correction station B is provided with a storage part, and the storage part is provided with storage slots with the same number as the number of memory sticks 100, and the released memory sticks 100 are released into each storage slot. The front and back detection mechanism 31 detects whether there is a memory stick 100 installed upside down among the memory sticks 100 located at the detection and correction station B. The front and back correction mechanism 32 lifts the memory stick 100 installed upside down to above other memory sticks 100 (i.e., the memory stick 100 with the front and back installed correctly at the detection and correction station B), and swaps the front and back of the memory stick 100 installed upside down so that the front and back of the memory stick 100 are installed correctly after the swap. Then, the front and back correction mechanism 32 resets the memory stick 100 with the front and back adjusted to the detection and correction station B. The transport robot 20 transports the clamping and pressing device 10 to the inspection and correction station B, clamps the memory stick 100 that has completed inspection and correction from the inspection and correction station B through the clamping mechanism 11, and transports the clamping and pressing device 10 to the assembly station C, the clamping mechanism 11 releases the memory stick 100 that has completed inspection and correction to the memory stick slot 200 of the assembly station C, and the pressing mechanism 12 presses the memory stick 100 that has completed inspection and correction into the memory stick slot 200 in sequence.

[0040] In a preferred embodiment, two inspection and correction stations B can be set. In this way, when the memory bar 100 is released to one of the inspection and correction stations B for the first time and inspected and corrected, the handling robot 20 can carry the clamping and pressing device 10 to the material picking station A to re-pick the material and carry it to another inspection and correction station B. Therefore, after the inspection and correction process of the first inspection and correction station B is completed, the handling robot 20 can carry the clamping and pressing device 10 to the inspection and correction station B that has completed the inspection and correction process, so as to clamp the memory bar 100 that has completed the inspection and correction process through the clamping mechanism 11, and carry it to the assembly station C for assembly of the memory bar 100. In this way, when one of the inspection and correction stations B is carrying out the inspection and correction process, the new memory bar 100 can be carried to another inspection and correction station B. Such alternating cycles can not only improve the handling efficiency of the handling robot 20, but also effectively improve the inspection and correction efficiency.

[0041] like Figure 2-Figure 6 As shown, the material clamping and pressing device 10 also includes: a pressing buffer mechanism 13, which includes: a fixed frame 131, a mobile frame 132, a plurality of sliding guide components 133, and an elastic buffer 134. In this embodiment, a connecting portion 127 for quick-release connection with the handling robot 20 is also provided on the fixed frame 131, and the setting of the connecting portion 127 enables the material clamping and pressing device 10 to be quickly connected with the handling robot 20. The pressing mechanism 12 is installed on the mobile frame 132, and the mobile frame 132 is located inside the frame body of the fixed frame 131, and the mobile frame 132 is located above the pressing mechanism 12; the mobile frame 132 can move relative to the fixed frame 131, and drive the pressing mechanism 12 to move synchronously. Each sliding guide component 133 is arranged between the mobile frame 132 and the fixed frame 131, and the sliding guide component 133 can guide the movement of the mobile frame 132 relative to the fixed frame 131. The elastic buffer 134 is disposed between the movable frame 132 and the fixed frame 131. If the memory stick 100 is stuck during the pressing process of the pressing mechanism 12, that is, the memory stick 100 cannot be pressed into the memory stick slot 200, the movable frame 132 moves in the opposite direction of the pressing under the action of the sliding guide assembly 133, and the sliding guide assembly 133 guides the movement of the movable frame 132. The elastic buffer 134 is used to buffer the reverse movement of the movable frame 132 to avoid damage to the memory stick 100.

[0042] In one embodiment, the press-fitting buffer mechanism 13 also includes: a pressure detection unit 135, which is disposed on the movable frame 132 and located between the movable frame 132 and the fixed frame 131. The pressure detection unit 135 is used to detect the magnitude of the reverse force applied to the movable frame 132 during the press-fitting process of the pressing mechanism 12.

[0043] Specifically, if empty material is pressed, the reaction force on the movable frame 132 detected by the pressure detection unit 135 is zero; if the press-fitting is normal, the reaction force on the movable frame 132 detected by the pressure detection unit 135 is the normal pressure of the press-fitting; if material is stuck, the reaction force on the movable frame 132 detected by the pressure detection unit 135 is abnormal and greater than the normal pressure of the press-fitting.

[0044] In some embodiments, a corresponding display module may be provided, and the display module may be connected to the pressure detection unit 135, and the display module may display the numerical value of the reaction force magnitude detected by the pressure detection unit 135 to the movable frame 132. Of course, a corresponding alarm module may also be provided, and the alarm module may set a preset pressure, which is the normal press-fitting pressure magnitude. When the magnitude of the reaction force magnitude detected to the movable frame 132 is zero, a first prompt signal may be used to prompt, when the magnitude of the reaction force magnitude detected to the movable frame 132 is the normal press-fitting pressure magnitude, a second prompt signal may be used to prompt, and when the magnitude of the reaction force magnitude detected to the movable frame 132 is abnormal and greater than the normal press-fitting pressure magnitude, a third prompt signal may be used to prompt. The first prompt signal, the second prompt signal, and the third prompt signal may be different sound signals, different light signals, or a combination of different sound signals and different light signals.

[0045] In the above embodiment, the sliding guide assembly 133 includes: a linear bearing 1331 and a sliding shaft 1332. The linear bearing 1331 is installed on the fixed frame 131. The sliding shaft 1332 can be slidably passed through the linear bearing, and a limiting portion is provided at the top end of the sliding shaft 1332. The limiting portion is located outside the linear bearing 1331 to limit the sliding of the sliding shaft 1332. The bottom end of the sliding shaft 1332 is connected to the movable frame 132.

[0046] like Fig. 9 and Fig.10 As shown, the clamping mechanism 11 includes: a guide rail 111, two sliders 112, two clamping claws 113, and a clamping claw driving assembly 114. The two sliders 112 are slidably arranged on the guide rail 111, and the two clamping claws 113 are respectively fixed on the two sliders 112. The clamping claw driving assembly 114 is used to drive the two sliders 112 to approach each other so that the two clamping claws 113 clamp the memory bar 100, or the clamping claw driving assembly 114 is used to drive the two sliders 112 to move away from each other so that the two clamping claws 113 release the memory bar 100.

[0047] In this embodiment, the clamping jaws 113 are provided with a plurality of clamping grooves 1131, and the clamping grooves 1131 are used to clamp the short side of the memory stick 100. When the two clamping jaws 113 are driven by the clamping jaw driving assembly 114 to approach the two sliders 112, the short side of the memory stick 100 is located in the clamping grooves 1131. When the two clamping jaws 113 are moved to a suitable position and the memory stick 100 is clamped, the memory stick 100 can be clamped by the clamping grooves 1131. By providing a plurality of clamping grooves 1131, a plurality of memory sticks 100 can be clamped each time.

[0048] In this embodiment, in order to ensure the stability of the sliding of the clamping jaws, two guide rails 111 are provided, and two sliders 112 are provided on each guide rail 111, wherein one clamping jaw 113 is fixed on the slider 112 on the same side of the two guide rails 111, and the other clamping jaw 113 is fixed on the slider 112 on the other side of the two guide rails 111.

The clamping in place detection member 1152 is set at the clamping position, wherein the clamping position is the position where the clamping claw 113 moves through the slider 112 to clamp the memory stick 100. The clamping in place detection sensor 1151 is a through-beam infrared sensor that can emit and receive infrared rays. The clamping in place detection member 1152 is used to block the infrared rays emitted by the clamping in place detection sensor 1151, so as to control the clamping claw driving assembly 114 to stop working through the clamping in place detection sensor 1151.

The release-in-place detection member 1162 is used to block the infrared rays emitted by the release-in-place detection sensor 1161, so as to control the clamping claw driving assembly 114 to stop working through the release-in-place detection sensor 1161.

[0051] In this embodiment, the clamping jaw driving assembly 114 is a bidirectional driving cylinder, which can drive the two sliders 112 on each guide rail 111 to move toward or away from each other.

[0055] The shaft driving assembly 122 is used to drive the shaft 121 to rotate around its own axis, so that each protrusion 1210 contacts each ejector pin 123 in sequence, and each ejector pin 123 moves downward in sequence, so as to press each memory module 100 into the memory module slot 200 in sequence. The ejector pin reset member 124 is used to reset the ejector pin 123, and the limiting member 1254 cooperates with the limiting protrusion 1230 to limit the reset position of the ejector pin 123.

[0056] In this embodiment, the protrusions 1210 are spirally arranged on the shaft body of the shaft 121, and the angles between two adjacent protrusions 1210 are the same. When not initially pressed, the shaft body of the shaft 121 contacts the ejector pin 123. During the rotation of the shaft 121, each protrusion 1210 on the shaft body sequentially touches the ejector pin 123 at the corresponding position, so that the ejector pin 123 corresponding to each protrusion 1210 can move downward to press the memory stick 100.

[0057] In this embodiment, two pressing mechanisms 12 are provided, and the two pressing mechanisms 12 are connected by a pulley. The two pressing mechanisms 12 can press the two ends of the memory stick 100 respectively to ensure that the memory stick 100 is evenly stressed.

[0058] In one embodiment, the rotating shaft 121 includes: a rotating shaft body 1211 and a plurality of pressing cams 1212, each pressing cam 1212 is coaxially installed on the rotating shaft body 1211, and a convex point 1210 is provided on the circumferential surface of the pressing cam 1212, and the convex points 1210 of each pressing cam 1212 installed on the rotating shaft body 1211 are distributed in a spiral manner.

[0059] Specifically, if N memory sticks 100 are to be press-fitted at the same time, N pressing cams 1212 need to be installed, but the angles of the protrusions on the pressing cams 1212 must be distributed in N+1. For example, when the design is capable of press-fitting two memory sticks 100 at the same time, the distribution of the protrusions 1210 on the pressing cams 1212 should be 360°÷(2+1)=120°. Although it is divided into three equal parts, only two pressing cams 1212 are installed. In this way, the number of pressing cams 1212 is 1 less than the number of equal parts of the angle, thereby generating a position relative to the protrusion 1210 but without the protrusion 1210. This position can be used as the origin position of the pressing cam 1212. When not initially press-fitted, the origin position can be made to fit the ejector pin 123. During installation, two adjacent pressing cams 1212 are offset by an angle, and so on, so that the protrusions 1210 of the pressing cams 1212 are distributed in a spiral manner. At the same time, since the bumps 1210 are offset from each other, the memory sticks 100 will not be pressed simultaneously during the press-installation process, so as to ensure the order of press-installation and to ensure that there is sufficient press-installation force during the press-installation process. At the same time, press-installation in sequence can disperse the press-installation force at different time points, reduce the instantaneous force on the motherboard, and thus avoid the motherboard from breaking due to excessive force.

[0060] like Figure 7 As shown, the pressing mechanism 12 also includes: bearing seats 126 arranged at both ends of each rotating shaft body 1211 to ensure that the rotating shaft body 1211 can rotate, and the two bearing seats 126 are fixed to the movable frame 132, so that the pressing mechanism 12 can be indirectly installed on the movable frame 132 to ensure that the pressing mechanism 12 can move synchronously with the movable frame 132.

[0061] In this embodiment, the material clamping and pressing device 10 also includes: a CCD visual positioning module 14, which is used to position the material picking station A, the detection and correction station B, and the assembly station C to ensure that the material clamping mechanism 11 can accurately clamp or release.

[0062] like Figure 11-Figure 15As shown, the front and back detection mechanism 31 includes: multiple groups of detection modules 311 and multiple storage parts 312, each group of detection modules 311 is arranged adjacent to each other in sequence, each group of detection modules 311 corresponds to a storage part 312, the detection module 311 is installed in the storage part 312, each storage part 312 is provided with a storage slot 3120 for accommodating the memory 100, and the bottom of the storage slot 3120 is provided with a positioning protrusion 3121, and the positioning protrusion 3121 is used to locate the anti-mistake notch of the memory stick 100. When the memory stick 100 is installed upside down, the positioning protrusion 3121 hinders the memory stick 100, so that the memory stick 100 protrudes outward relative to the storage slot 3120, and the detection module 311 is used to detect whether the memory stick 100 protrudes outward to the outside of the storage slot 3120, so as to determine whether the front and back of the memory stick 100 are installed upside down.

[0063] In this embodiment, the detection module 311 includes: a detection signal transmitting unit 3111, a detection signal receiving unit 3112, and two support seats 3113. The two support seats 3113 are respectively arranged at both ends of the length direction of the storage slot 3120. The length direction of the storage slot 3120 is the length direction of the memory stick 100. The detection signal transmitting unit 3111 and the detection signal receiving unit 3112 are respectively installed on the two support seats 3113. The detection signal transmitting unit 3111 is used to transmit the detection signal, and the detection signal receiving unit 3112 is used to receive The detection signal emitted by the detection signal emitting unit 3111, when the memory stick 100 is installed upside down, under the action of the positioning protrusion, the memory stick 100 protrudes outward to the outside of the storage slot 3120 (that is, the positioning protrusion 3121 does not fit into the anti-foolproof notch of the memory stick 100, but directly abuts against the edge of the memory stick 100, thereby lifting the memory stick 100 to the outside of the storage slot 3120), thereby blocking the detection signal receiving unit 3112 from receiving the detection signal emitted by the detection signal emitting unit 3111, thereby determining that the memory stick 100 is installed upside down.

[0064] like Fig.11As shown, the forward and reverse correction mechanism 32 includes: a plurality of guide rods 321, a correction moving mechanism 322, a correction lifting mechanism 323 and a correction rotating mechanism 324; each guide rod 321 corresponds to a placement portion 312, and the top end of the guide rod 321 is connected to the bottom end of the placement portion 312, the correction lifting mechanism 323 is arranged at the power output end of the correction moving mechanism 322, the correction rotating mechanism 324 is arranged at the power output end of the correction lifting mechanism 323, and the correction moving mechanism 322 is used to drive the correction lifting mechanism 323 to move and drive the correction rotating mechanism 324 to move to the bottom end of the guide rod 321 below the placement part 312 where the memory stick 100 is installed upside down. The correction lifting mechanism 323 drives the correction rotating mechanism 324 to move upward, so as to drive the placement part 312 where the memory stick 100 is installed upside down to move upward to the top of other placement parts 312 through the guide rod 321, so that the memory stick 100 installed upside down is located above other memory sticks 100. Then, the correction rotating mechanism 324 drives the guide rod 321 to rotate 180° around its axis to adjust the front and back of the memory stick 100.

[0065] In one embodiment, the front and back correction mechanism 32 also includes: a plurality of guide rod reset members 325, each guide rod reset member 325 corresponds to a guide rod 321, and the guide rod reset member 325 is preferably a spring. The guide rod reset member 325 is used to reset the guide rod after the correction rotation mechanism 324 drives the guide rod to rotate 180° around its axial direction to adjust the front and back sides of the memory stick 100.

[0066] The detection and correction device 30 also includes: a scanning mechanism 33 and a step plate 34. The step plate 34 is provided with a plurality of steps 340, each step 340 corresponds to a guide rod 321, and the step plate 34 is arranged at the power output end of the correction lifting mechanism 323. The correction moving mechanism 322 is also used to drive the correction lifting mechanism 323 to drive the step plate 34 to move below the bottom end of the guide rod 321, and make each step 340 of the step plate 34 located below the bottom end of the corresponding guide rod 321. The correction lifting mechanism 323 is also used to drive the step plate 34 to move upward, so as to lift each guide rod 321 through each step 340, so that the memory bars 100 in the storage portion 312 are distributed in a stepped shape. A QR code or a barcode is set on the front of the memory stick 100. After front and back correction, the front sides of the memory sticks 100 arranged in a step shape are all facing the scanning mechanism 33. The scanning mechanism 33 is used to scan the QR code or the barcode on the memory sticks 100 arranged in a step shape, wherein the QR code or the barcode stores information of the memory stick, such as storage space, manufacturer, etc.

[0067] In one embodiment, the detection and correction device 30 also includes: a recovery tray 35. When the scanning mechanism 33 scans one or more memory bars 100 and the information of the QR code or barcode is incorrect, for example, the storage space does not match the actual product, the clamping mechanism 11 of the clamping and pressing device 10 can be used by the handling robot 20 to move the memory bars 100 in each storage slot 3120 currently scanned to the recovery tray 35 for recovery, and the memory bars 100 with normal scanning and abnormal scanning can be manually distinguished in the recovery tray 35.

[0068] It should be noted that if 8 storage slots 3120 are provided and a memory stick 100 is inserted into each storage slot 3120, when the information of the QR code or bar code of one or two or other number of memory sticks 100 scanned by the scanning mechanism 33 is abnormal, the 8 memory sticks 100 scanned this time are moved to the recovery tray 35 for recovery through the clamping mechanism 11.
