Description

Technical Field

[0001] The invention belongs to the technical field of memory stick testing equipment, and in particular relates to an automatic plug-in and pull-out grasping mechanism for a memory stick. Background Art

[0002] After the memory stick is produced, there will be a testing phase. The purpose of the test is to check the memory capacity, data access speed, etc. It is usually tested using a special memory stick test device. During the test, the memory stick to be tested needs to be inserted into the memory stick test device, and the memory stick is unplugged from the test device after the test is completed. In the current memory stick testing process, a large amount of testing work is done through manual plug-in and unplug testing, and plug-in and unplug testing is not implemented in an automated manner. This is mainly because the difficulty of automated plug-in and unplugging lies in realizing the automatic plug-in and unplugging of the memory stick while not damaging the quality of the memory stick. However, the current manual plug-in and unplugging method for memory stick testing is inefficient, and due to plug-in and unplugging techniques, for example, in order to pursue plug-in and unplugging speed, the memory stick is accidentally plugged in and out in a tilted state, which will cause problems such as scratches on the gold fingers during the memory stick testing process, affecting the quality.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] In one embodiment, a memory stick automatic plug-in and pull-out grabbing mechanism is provided. Figure 1-3 As shown, the memory stick automatic plug-in and pull-out grabbing mechanism includes a support plate 1, which is a horizontal metal plate that mainly supports other components. A clamping claw structure is provided on the lower side of the support plate 1, and the memory stick is grabbed and released by the clamping claw structure. The clamping claw structure includes a guide linear slide 2 vertically arranged on the lower side of the support plate 1, and a mounting mainboard 3 assembled on the guide linear slide 2 through a vertical slider 21. The mounting mainboard 3 is a vertically arranged metal plate. A vertical pushing cylinder 31 is provided on the mounting mainboard 3. The upper end of the piston rod at the top of the pushing cylinder 31 is connected to the lower side of the support plate 1. When the piston rod of the pushing cylinder 31 is extended, it can drive the mounting mainboard 3 to move downward along the guide linear slide 2.

[0034] like Figure 1-3 As shown, a horizontal clamping claw guide linear slide 32 is provided at the lower part of the mounting mainboard 3, and a first horizontal slider 33 and a second horizontal slider 34 mounted on the clamping claw guide linear slide 32 are provided on both sides of the lower part of the mounting mainboard 3, respectively. The clamping claw guide linear slide 32 has two sections, which are arranged on the left and right sides of the lower part of the mounting mainboard 3, respectively. The first horizontal slider 33 and the second horizontal slider 34 are respectively installed on the two sections of the clamping claw guide linear slide 32 on the left and right sides. Left and right opposing clamping claws 35 are provided on the lower sides of the first horizontal slider 33 and the second horizontal slider 34, respectively. The clamping claw 35 includes a clamping claw main body, which is a roughly L-shaped metal plate, and a clamping plate 351 extending downward is provided on the outer side of the clamping claw main body, and the clamping plate 351 is used to clamp the side of the memory stick 4.

[0035] Combination Figure 3 As shown, a clamping push spring 36 ( Figure 3 The spring in the figure serves as a diagram and does not represent the actual structure of the spring). A clamping push spring 36 is distributed on the upper and lower sides of the clamping claw guiding linear slide rail 32, and a spring seat 37 is provided on the side of the mounting main board 3. The outer side of the clamping push spring 36 presses on the spring seat 37, and the inner side corresponds to the outer side surface of the first transverse slider 33 and the second transverse slider 34. The clamping push spring 36 is used to apply a clamping force inward (in the direction of moving toward each other) to the first transverse slider 33 and the second transverse slider 34. The clamping push spring 36 can be installed in the following manner: a spring guide rod corresponding to the clamping push spring 36 is set inside the spring seat 37, a spring guide rod is set on the upper and lower sides of the clamping claw guide linear slide 32, the clamping push spring 36 is sleeved on the corresponding spring guide rod, and a hole corresponding to the spring guide rod is set on the first transverse slider 33 and the second transverse slider 34. When the first transverse slider 33 and the second transverse slider 34 slide to both sides, the corresponding clamping push spring 36 will press against the outside of the first transverse slider 33 and the second transverse slider 34 and be compressed, and the spring guide rod will pass through the corresponding hole without interference. The clamping push spring 36 can also be installed in other ways, as long as it can apply a rebound force to the first transverse slider 33 and the second transverse slider 34 so that the two clamping claws 35 are closed.

[0036] like Figure 1-3 As shown, a vertical jaw pushing cylinder 5 is also provided on the mounting main board 3, and a jaw pushing plate 51 is connected to the bottom of the jaw pushing cylinder 5. The lower part of the jaw pushing plate 51 gradually narrows downward, so that the lower sides of the jaw pushing plate 51 are inclined surfaces, so that the first horizontal slider 33 and the second horizontal slider 34 can be pushed to move to both sides when moving downward, so that the two jaws 35 can be opened.

[0037] Combination Figure 1-3 As shown, the working mode of the memory bar automatic plug-in and pull-out grabbing mechanism is as follows:

[0038] The memory stick automatic plug-in grabbing mechanism is used in conjunction with a manipulator. The memory stick automatic plug-in grabbing mechanism grabs the memory stick to be tested. Then, the manipulator moves the memory stick automatic plug-in grabbing mechanism with the memory stick to be tested to the top of the slot of the memory stick testing device. The memory stick automatic plug-in grabbing mechanism inserts the memory stick to be tested into the slot. When the memory stick to be tested is tested, the manipulator carries the memory stick automatic plug-in grabbing mechanism to remove the tested memory stick from the slot and moves it to the storage area for the tested memory stick. During this process, the memory stick automatic plug-in grabbing mechanism clamps and releases the memory stick in the following manner: (1) When it is necessary to clamp the memory stick 4 to be tested, the clamping jaw push-out cylinder 5 extends to drive the clamping jaw push-out plate 51 to move downward. The clamping jaw push-out plate 51 extends between the first horizontal slider 33 and the second horizontal slider 34. Since the lower two sides of the clamping jaw push-out plate 51 are inclined surfaces, the first horizontal slider 33 and the second horizontal slider 34 will be pushed to move to both sides, thereby driving the two clamping jaws 35 to open. Open; then push the cylinder 31 to extend and drive the mounting mainboard 3 to move downward along the guide linear slide rail 2, so that the clamping plate parts 351 of the two clamping jaws 35 are respectively located on the left and right sides of the memory stick 4 to be tested, and then control the clamping jaw pushing cylinder 5 to retract and drive the clamping jaw pushing plate 51 to move upward, and the clamping jaw pushing plate 51 is withdrawn from between the first horizontal slider 33 and the second horizontal slider 34. Since there is no clamping jaw pushing plate 51 to resist, the first horizontal slider 33 and the second horizontal slider 34 will be pushed inward (the direction in which the two clamping jaws move toward each other) by the corresponding clamping pushing springs 36, so that the two clamping jaws 35 clamp the memory stick 4 to be tested on the left and right sides respectively, so as to grasp the memory stick 4 to be tested. (2) When it is necessary to release the memory stick 4 to be tested, the jaw push cylinder 5 extends to drive the jaw push plate 51 to move downward, and the jaw push plate 51 extends between the first transverse slider 33 and the second transverse slider 34. Since the lower two sides of the jaw push plate 51 are inclined surfaces, the first transverse slider 33 and the second transverse slider 34 will be pushed to move to both sides, thereby driving the two jaws 35 to open and release the memory stick 4 to be tested.

[0039] The automatic insertion and extraction grasping mechanism of the memory stick uses a special clamping claw to grasp the memory stick. The automatic insertion and extraction grasping mechanism of the memory stick solves the problem that a large number of memory stick tests in the current market use manual insertion and extraction tests, can ensure the uniformity of the insertion and extraction actions, effectively reduce the damage to the memory stick caused by the irregular insertion and extraction actions, avoid various problems caused by manual insertion and extraction, and use the clamping claw to perform automatic grasping and releasing actions instead of manual work, which can work 24 hours a day and improve the test efficiency. By arranging clamping pushing springs 36 on both sides of the clamping claw 35, the clamping method of the clamping claw 35 is to push forward with the spring flexibility, so as to ensure that the memory stick is clamped with appropriate force so as not to clamp the product.

[0040] Further, combined with Figure 1-2As shown, in one embodiment, the memory bar automatic plug-in and pull-out grabbing mechanism is provided with vertical push guide rods 6 on both sides of the mounting mainboard 3. The push guide rods 6 provided here are mainly used in conjunction with the plug-in test fixture on the memory bar test device. Lock buckles for pressing the memory bar to be tested are provided on both sides of the memory bar slot on the plug-in test fixture. The push guide rods 6 are used to push open the buckles when inserting or removing the memory bar. A guide rod propulsion cylinder 61 is provided on the support plate 1. Each push guide rod 6 is equipped with a guide rod propulsion cylinder 61. The piston rod of the guide rod propulsion cylinder 61 extends to the lower side of the support plate 1. The top of the push guide rod 6 is connected to the piston head at the lower end of the guide rod propulsion cylinder 61. Bearing seats 62 are provided on both sides of the mounting mainboard 3. The bearing seats 62 are fixed on the side of the mounting mainboard 3. Linear bearings 63 are provided in the bearing seats 62. The push guide rods 6 are correspondingly arranged in the linear bearings 63. The linear bearings 63 play a role in guiding the push guide rods 6. A metal pressing head 64 is provided at the bottom of the pushing guide rod 6. By providing the metal pressing head 64, the relative hardness of the metal material is increased, thereby better increasing the effect and service life of the pressing lock buckle.

[0041] By setting a pushing guide rod 6 and a guide rod pushing cylinder 61, the memory stick automatic plug-in and pull-out grasping mechanism can cooperate with the plug-in test tooling to realize automatic unlocking of the lock. When the memory stick 4 to be tested is tested on the motherboard of the test equipment, the lock can be pushed open by pushing the guide rod 6, and the memory stick to be tested can be inserted into the slot. Then, the pushing guide rod 6 is removed so that the two sides of the memory stick 4 to be tested are locked by the lock. After the test of the memory stick 4 to be tested on the motherboard of the test equipment is completed, the lock can be pushed open by pushing the guide rod 6 to take out the memory stick after the test is completed.

[0042] Further, combined with Figure 1-3 As shown, in one embodiment, the memory stick automatic plug-in and pull-out grasping mechanism is provided with a reflective fiber optic sensor 41 at the bottom of the mounting motherboard 3, and the reflective fiber optic sensor 41 is fixed to the bottom of the mounting motherboard 3 through an L-shaped plate. The reflective fiber optic sensor 41 is located next to the grasping position of the memory stick 4 to be tested. When the clamp 35 clamps the memory stick 4 to be tested, the reflective fiber optic sensor 41 senses a signal and feeds back to the controller that controls the memory stick automatic plug-in and pull-out grasping mechanism to perform related actions.

[0043] Further, combined with Figure 1-2 As shown, in one embodiment, the memory stick automatic plug-in and pull-out grasping mechanism is provided with a manipulator connecting sleeve 11 on the top of the support plate 1, and an expansion joint is provided on the manipulator connecting sleeve 11. The manipulator connecting sleeve 11 is used to be installed on the connecting rod of the manipulator in a tight fit manner.

[0044] Further, combined with Figure 1-3As shown, in one embodiment, the memory stick automatic plug-in and pull-out grasping mechanism is provided with rollers 52 for contacting the clamping claw pushing plate on the inner top of the first transverse slider 33 and the second transverse slider 34, and a corresponding roller groove is provided on the inner top of the first transverse slider 33 and the second transverse slider 34, and the roller 52 is installed in the corresponding roller groove through a rotating shaft. When the clamping claw pushing plate 51 moves downward, the roller 52 contacts the inclined surface at the bottom of the clamping claw pushing plate 51, and the rolling contact method can reduce friction, which is conducive to easily pushing the two clamping claws 35 apart.

[0045] Further, combined with Figure 1-3 As shown, in one embodiment, the memory stick automatic plug-in and pull-out grasping mechanism is provided with a stroke adjustment mechanism on the inner side of the first transverse slider 33 and the second transverse slider 34 respectively, and the stroke adjustment mechanism includes an adjusting screw 38 and a screw seat 39, the screw seat 39 is arranged on the mounting main board 3, and the adjusting screw 38 is arranged on the screw seat 39. By adjusting the depth of the adjusting screw 38 screwed into the screw seat 39, the left and right moving position of the first transverse slider 33 can be adjusted, and the second transverse slider 34 can also be adjusted in a corresponding manner, so that the clamp 35 can grasp the memory sticks 4 to be tested of different sizes.

[0046] Further, combined with Figure 1-2 As shown, in one embodiment, the memory bar automatic plug-in grabbing mechanism is provided with two sets of clamping claw structures side by side on the lower side of the support plate 1, so that the memory bar automatic plug-in grabbing mechanism can grab a single or double memory bar to be tested as needed. In other embodiments, other numbers of clamping claw structures can also be provided as needed.

[0047] In one embodiment, a memory bar automatic plug-in and pull-out grabbing device is provided, Figure 1-6 As shown, the memory stick automatic plug-in grabbing device includes a manipulator 7. The manipulator 7 of the memory stick automatic plug-in grabbing device is a four-axis manipulator. The four-axis manipulator can meet the requirements of grabbing and spatial positioning of the memory stick 4 to be tested during testing. The memory stick automatic plug-in grabbing mechanism in the previous embodiment is provided on the manipulator 7. The memory stick automatic plug-in grabbing mechanism is connected to the connecting shaft 71 at the end of the manipulator 7 through the manipulator connecting sleeve 11 thereon. The memory stick automatic plug-in grabbing device also includes a plug-in test fixture provided next to the manipulator. The plug-in test fixture is a component on the mainboard of the memory stick testing device, such as Figure 5As shown, the plug-in test fixture includes a base plate 8, on which a card slot 81 for inserting a memory stick to be tested is provided, and two card slots 81 are provided in parallel. On both sides of the card slot 81, there are resettable locks 82 for pressing the memory stick 4 to be tested. When the manipulator 7 carries the memory stick automatic plug-in and pull-out grasping mechanism to grab the memory stick 4 to be tested and place it in the card slot 81, the locks 82 are pushed open by the lower end of the guide rod 6. After the memory stick 4 to be tested is inserted into the card slot 81, the memory stick 4 to be tested is locked by the locks 82 on both sides to keep the memory stick 4 to be tested stable. A memory stick ejection component is also provided on the plug-in test fixture. When the memory stick 4 to be tested is tested, the manipulator 7 carries the memory stick automatic plug-in and pull-out grasping mechanism to grab the memory stick 4 to be tested, and the locks 82 are pushed open by the lower end of the guide rod 6. At this time, the memory stick 4 to be tested can be ejected by the memory stick ejection component, and the memory stick automatic plug-in and pull-out grasping mechanism can grab the memory stick 4 to be tested and move it away.

[0048] In one embodiment, a lock buckle 82 of the following structure may be used, which includes a rotatable locking rod, a rotating shaft is arranged at the bottom of the locking rod, a torsion spring is arranged on the rotating shaft, a torsion spring seat is arranged on the bottom plate 8, and the locking rod is installed on the torsion spring seat through the torsion spring, so that the locking rod of the lock buckle 82 can be rotated left and right and can be reset by the torsion spring, and a roller is arranged on the top of the locking rod, and the two sides of the memory stick 4 to be tested are pressed by the roller.

[0049] In one embodiment, a memory stick ejection component of the following structure may be used, wherein the memory stick ejection component is a pressing plate 83, a guide rod plugged into the bottom plate 8 is provided at the bottom of the pressing plate 83, a spring is provided between the pressing plate 83 and the bottom plate 8, a slot corresponding to the memory stick 4 to be tested is provided on the inner side of the pressing plate 83, when the memory stick 4 to be tested is inserted into the slot 81, the right side of the memory stick 4 to be tested is locked by the lock buckle 82, the left side of the memory stick 4 to be tested is located in the slot of the pressing plate 83, and the pressing plate 83 is locked by the lock buckle 82 on the left side, so that the memory stick 4 to be tested is stably installed in the slot 81. When the lock buckles 82 on both sides are pushed open by pushing the lower end of the guide rod 6, the pressing plate 83 will be rebounded, driving the memory stick 4 to be tested to be ejected from the slot 81.

[0050] Based on the above embodiments, it can be known that the memory bar automatic plug-in grabbing device can automatically grab the memory bar 4 to be tested and insert it into the special memory bar test interface (slot 81) on the mainboard of the memory bar test equipment, and can remove the memory bar after the test. The main working mode of the memory bar automatic plug-in grabbing device is: the portable memory bar automatic plug-in grabbing mechanism installed on the four-axis manipulator can complete the material grabbing (the material is the memory bar to be tested or the memory bar after the test on the mainboard) by controlling the opening and closing of the clamping claw 35. When inserting the memory bar 4 to be tested, the lock buckle 82 can be pushed open by pushing the lower end of the guide rod 6. During the test, the two sides of the memory bar are stuck by the lock buckle 82. The material of the pressure head at the lower end of the guide rod 6 is metal material, and the relative hardness is increased, which better increases the unlocking effect of the pressure lock buckle and extends the service life. After the test is completed, the lock buckles 82 on both sides of the memory bar can be pushed open by pushing the guide rod 6. After the memory bar is ejected, it is grabbed and removed by the memory bar automatic plug-in grabbing device. The clamping method of the clamping claw 35 on the memory stick automatic plug-in and pull-out gripping mechanism is spring-flexible propulsion, ensuring that the memory stick is clamped with appropriate force without damaging the product. The memory stick automatic plug-in and pull-out gripping device changes the current low efficiency of manual plug-in and pull-out testing and the risk of memory stick damage during testing.

[0051] In one embodiment, a method for automatically plugging and pulling out a memory stick is provided. The method uses the automatic plugging and pulling out device for pulling out a memory stick in the previous embodiment. The method includes the following steps:

[0052] (1) The produced memory stick to be tested is placed on the shelf, and the mechanical arm 7 carries the memory stick automatic plug-in and pull-out grasping mechanism to move to the top of the memory stick to be tested 4. The clamping jaw pushing cylinder 5 extends to drive the clamping jaw pushing plate 51 to move downward, and the clamping jaw pushing plate 51 extends between the first horizontal slider 33 and the second horizontal slider 34. The first horizontal slider 33 and the second horizontal slider 34 are pushed to move to both sides, and the two clamping jaws 35 open.
