Description

Technical Field

[0001] This utility model relates to the technical field of distance measurement, and in particular to a dual-station spring adjustment device. Background Technology

[0002] In semiconductor equipment wafer sorting, sorting machines are required for sorting. During the sorting process, the sorting machine uses a swing arm suction nozzle mechanism to transfer the wafers. In order to improve the wafer transfer speed, a swing arm suction nozzle mechanism with a double swing arm structure is usually used.

[0003] Reference Figure 1 In related technologies, the swing arm suction nozzle mechanism includes a base 100 and two swing arm suction nozzle assemblies 110 symmetrically arranged on the base 100. Each swing arm suction nozzle assembly 110 includes a first swing arm 120, a first suction nozzle 130, and a spring 140. The first suction nozzle 130 is located at the top of the first swing arm 120, and the spring 140 connects the bottom of the first swing arm 120 to the base 100. A spring 150 and a limiting screw 160 are also provided between the first swing arm 120 and the base 100. The spring 150 is used to drive the first swing arm 120. The first swing arm 120 swings away from the base 100. The limiting screw 160 is used to limit the swing position of the first swing arm 120 away from the base 100. The base 100 is also provided with an adjusting screw 170 and an adjusting locking nut 180. The adjusting screw 170 and the adjusting locking nut 180 work together to adjust the compression of the spring 150. The limiting screw 160 is also provided with a limiting locking nut 190. The limiting locking nut 190 is used to adjust the limiting position of the limiting screw 160 on the first swing arm 120.

[0004] When the first suction nozzle 130 is picking up wafer chips, the chip exerts a force P on the first suction nozzle 130. This force P also drives the first suction nozzle 130 to move closer to the base 100, thereby separating the first swing arm 120 from the limiting screw 160. This force P is the resultant force of the combined action of the spring 140 and the spring 150.

[0005] Ideally, when the spring 140 is vertical, it is in a free state, and P is the force of the spring 150, with the spring 140's force accounting for zero in P. To ensure consistent adjustment of the two swing arm suction nozzle assemblies 110, when the spring 150 of both assemblies 110 has the same compression, the separation force on the first suction nozzle 130 of both assemblies 110 is the same when the first swing arm 120 separates from the limiting screw 160. However, in actual assembly, due to factors such as spring 140 tolerance and deformation, the spring 140 is not vertical when the spring 150 and limiting screw 160 are not installed on the swing arm suction nozzle assembly 110. This results in different spring 150 compressions for the two assemblies 110 when the first suction nozzle 130 requires the same separation force.

[0006] Reference Figure 2 In order to ensure the symmetry and consistency of the two swing arm suction nozzle assemblies 110 of the swing arm suction nozzle mechanism, the spring 140 of the swing arm 200 to be adjusted needs to be adjusted when the spring 150 and the limit screw 160 are not installed on the swing arm suction nozzle assembly 110.

[0007] However, the existing spring 140 adjustment method can only adjust the spring 140 of one swing arm nozzle assembly 110 at a time, which is inefficient. Utility Model Content

[0008] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a dual-station spring adjustment device, which can simultaneously adjust the springs of the two swing arm suction nozzle assemblies of the swing arm suction nozzle mechanism, thereby improving adjustment efficiency.

[0009] A dual-station spring adjustment device according to an embodiment of the present invention includes:

[0010] Guide rails, extending left and right;

[0011] The feeding assembly includes a feeding slider, which has a positioning part for positioning and installing the swing arm to be adjusted. The feeding slider slides along the guide rail to transport the swing arm to be adjusted for loading and unloading.

[0012] Two measuring and adjusting mechanisms are provided, symmetrically arranged along the guide rail. Each mechanism is used to adjust the spring clips of the two arm suction nozzle assemblies of the arm to be adjusted. Each measuring and adjusting mechanism includes a displacement measuring head, an adjusting block, an adjusting motor, and an adjusting control module. The displacement measuring head detects the position of the first arm of the arm to be adjusted. The adjusting motor drives the adjusting block to push the first arm to adjust the spring clips. The adjusting control module receives the measurement information from the displacement measuring head and the motion data from the adjusting motor, calculates the spring clip adjustment amount, and controls the adjusting motor to adjust the spring clips according to the adjustment amount.

[0013] A dual-station spring adjustment device according to an embodiment of the present utility model has at least the following beneficial effects:

[0014] 1. This utility model, by setting a guide rail and a feeding assembly, with the guide rail extending left and right, and the feeding assembly including a feeding slider, which has a positioning part for positioning and installing the swing arm to be adjusted, slides along the guide rail to transport the swing arm to be adjusted for loading and unloading. It can be understood that by using the positioning part to accurately position the swing arm to be adjusted on the feeding slider, and then using the guide rail to guide the feeding slider to move for loading and unloading, the loading and unloading efficiency of the swing arm to be adjusted can be improved while ensuring the accurate positioning of the swing arm to be adjusted.

[0015] 2. This utility model sets up two measuring and adjusting mechanisms, which are symmetrically arranged along the guide rail. The two measuring and adjusting mechanisms are used to adjust the springs of the two swing arm suction nozzle assemblies of the swing arm to be adjusted. It can be understood that when the feeding slider moves the swing arm to be adjusted to the measuring and adjusting station, the two measuring and adjusting mechanisms can simultaneously adjust the springs of the two swing arm suction nozzle assemblies of the swing arm to be adjusted, which is beneficial to improving the adjustment efficiency.

[0016] 3. This utility model includes a displacement measuring head, an adjusting block, an adjusting motor, and an adjusting control module in its measuring and adjusting mechanism. The displacement measuring head is used to detect the position of the first swing arm to be adjusted. The adjusting motor is used to drive the adjusting block to push the first swing arm to adjust the spring. The adjusting control module is used to receive the measurement information from the displacement measuring head and the motion data from the adjusting motor to calculate the spring adjustment amount and control the adjusting motor to adjust the spring according to the spring adjustment amount. It can be understood that the displacement measuring head is used to measure the position of the first swing arm to detect the deformation of the spring. Then, the adjusting control module calculates the spring adjustment amount based on the measurement information from the displacement measuring head and the motion data from the adjusting motor and controls the adjusting motor to adjust the spring according to the spring adjustment amount. Thus, the deformation of the spring is automatically detected and the spring is automatically adjusted, thereby improving the spring adjustment efficiency.

[0017] According to some embodiments of the present invention, the feeding slider is provided with a plurality of positioning parts, which are arranged sequentially along the length direction of the guide rail.

[0018] The advantages of this invention are: by setting multiple positioning parts on the feeding slider, and arranging these positioning parts sequentially along the length of the guide rail, multiple swing arms to be adjusted can be continuously adjusted after the feeding slider has completed the installation of the swing arms to be adjusted, thus reducing the frequency of the device stopping to install the swing arms to be adjusted and improving efficiency.

[0019] According to some embodiments of the present invention, the feeding assembly includes a drive motor and a timing belt, the timing belt being used for transmission between the drive motor and the feeding slider, and the drive motor being used to drive the feeding slider to slide.

[0020] The advantage of this invention is that by including a drive motor and a timing belt in the feeding assembly, with the timing belt used for transmission between the drive motor and the feeding slider, and the drive motor used for driving the feeding slider to slide, the movement of the feeding slider can be made more precise by using the drive motor and timing belt in combination.

[0021] According to some embodiments of the present invention, two feeding components are provided, and the two feeding components alternately feed the material to be adjusted onto and off the swing arm.

[0022] The advantages of this invention are: by setting up two feeding components, which alternately feed the swing arm to be adjusted onto and off the device, it can be understood that while one feeding component is adjusting the spring, the adjusted swing arm to be adjusted and the new swing arm to be adjusted can be disassembled and installed on the other feeding component at the same time. Thus, the two feeding components can adjust the spring and disassemble and install the swing arm to be adjusted simultaneously, eliminating the need to stop the machine to disassemble and install the swing arm to be adjusted, thereby improving the working efficiency of the adjustment device.

[0023] According to some embodiments of the present invention, the feeding slider of one feeding assembly is provided with an anti-collision baffle, and the feeding slider of another feeding assembly is provided with an anti-collision photoelectric switch. The anti-collision baffle and the anti-collision photoelectric switch cooperate to sense and limit the movement to prevent the two feeding sliders from colliding.

[0024] The advantage of this invention is that it provides an anti-collision baffle on the feeding slider of one feeding assembly and an anti-collision photoelectric switch on the feeding slider of another feeding assembly. The anti-collision baffle and the anti-collision photoelectric switch work together to sense and limit the movement of the two feeding sliders to prevent them from colliding. It can be understood that before the two feeding sliders collide, the anti-collision baffle and the anti-collision photoelectric switch sense each other and control the two feeding sliders to stop moving to prevent them from colliding, thereby avoiding damage to the two feeding sliders from colliding with each other.

[0025] According to some embodiments of this utility model, the guide rail is provided with a left limit photoelectric switch and a right limit photoelectric switch, and the feeding slider is provided with a limit baffle. The left limit photoelectric switch and the right limit photoelectric switch cooperate with the limit baffle to sense and limit the maximum sliding position of the feeding slider.

[0026] The advantages of this invention are: by setting a left limit photoelectric switch and a right limit photoelectric switch on the guide rail, and setting a limit baffle on the feeding slider, the left limit photoelectric switch and the right limit photoelectric switch cooperate with the limit baffle to sense and limit the maximum sliding position of the feeding slider. It can be understood that by using the left limit photoelectric switch and the right limit photoelectric switch to cooperate with the limit baffle to sense and limit the maximum sliding position of the feeding slider, it is possible to avoid the feeding slider from sliding beyond the maximum sliding position and interfering with or colliding with other components and being damaged.

[0027] According to some embodiments of this utility model, the guide rail is provided with an origin photoelectric switch, the feeding slider is provided with a limit stop, and the origin photoelectric switch and the limit stop cooperate to sense and locate the origin position of the feeding slider.

[0028] The advantage of this invention is that by setting an origin photoelectric switch on the guide rail and setting a limit stop on the feeding slider, the origin photoelectric switch and the limit stop work together to sense and locate the origin position of the feeding slider. It can be understood that when the program is started, the feeding slider needs to be set to the coordinate origin from the origin photoelectric switch in sequence to ensure that the same coordinate position of the feeding slider can be maintained each time it is restarted.

[0029] According to some embodiments of the present invention, the adjusting block is provided with an opening groove on the left or right side, the opening groove accommodates the first swing arm of the swing arm to be adjusted, and the front and rear sides of the opening groove respectively abut against the first swing arm to push the first swing arm back and forth.

[0030] The advantage of this invention is that an opening groove is provided on the left or right side of the adjusting block. The opening groove accommodates the first swing arm to be adjusted. The front and rear sides of the opening groove abut against the first swing arm and push the first swing arm forward and backward. It can be understood that the opening groove has an opening that allows the first swing arm to enter the opening groove. Then, the opening groove utilizes the front and rear side walls to abut against and push the first swing arm when the adjusting block moves forward and backward.

[0031] According to some embodiments of the present invention, the measuring and adjusting mechanism further includes a support frame, a lifting frame, a translation frame, and a mounting frame. The lifting frame is slidably mounted on the support frame, the translation frame is slidably mounted on the lifting frame, the mounting frame is slidably mounted on the translation frame, the adjusting block is mounted on the mounting frame, and the adjusting motor is mounted on the translation frame. The adjusting motor drives the mounting frame to move back and forth to move the adjusting block back and forth.

[0032] The advantages of this invention are that the measuring and adjusting mechanism further includes a support frame, a lifting frame, a translation frame, and a mounting frame. The lifting frame is slidably mounted on the support frame, the translation frame is slidably mounted on the lifting frame, and the mounting frame is slidably mounted on the translation frame. The adjusting block is mounted on the mounting frame, and the adjusting motor is mounted on the translation frame. The adjusting motor drives the mounting frame to move back and forth, thereby causing the adjusting block to move back and forth. Thus, the adjusting block can change its height, left and right, and front and back positions through the cooperation of the lifting frame, translation frame, and mounting frame. Consequently, the position of the adjusting block can adapt to the position of the swing arm to be adjusted on the feeding slider.

[0033] According to some embodiments of the present invention, a first adjusting knob is threadedly connected to the support frame. The first adjusting knob is used to abut against the lifting frame to adjust and position the height of the lifting frame. A second adjusting knob is threadedly connected to the lifting frame. The second adjusting knob is used to abut against the translation frame to adjust and position the left and right positions of the translation frame.

[0034] The advantages of this invention are: by threading a first adjusting knob onto the support frame, which abuts against the lifting frame to adjust and position the height of the lifting frame, and threading a second adjusting knob onto the lifting frame, which abuts against the translation frame to adjust and position the left and right sides of the translation frame, the height of the lifting frame is positioned using the first adjusting knob, and the left and right sides of the translation frame are positioned using the second adjusting knob. This makes the adjustment of the height and left and right positions of the adjusting block more accurate.

[0035] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0051] A dual-station spring adjustment device according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0052] This utility model aims to provide an embodiment of a dual-station spring adjustment device.

[0053] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, a dual-station spring adjustment device mainly includes a guide rail 210, a feeding assembly 220, and a measuring and adjusting mechanism 250.

[0054] For guide rail 210, guide rail 210 is set to extend to the left and right.

[0055] For the feeding assembly 220, the feeding assembly 220 includes a feeding slider 230, which has a positioning part 240 for positioning and installing the swing arm 200 to be adjusted. The feeding slider 230 slides along the guide rail 210 to transport the swing arm 200 to be adjusted for loading and unloading.

[0056] It is understandable that by using the positioning part 240 to accurately position the swing arm 200 to be adjusted on the feeding slider 230, and then using the guide rail 210 to guide the feeding slider 230 to move for loading and unloading, the loading and unloading efficiency of the swing arm 200 to be adjusted can be improved while ensuring the accurate positioning of the swing arm 200 to be adjusted.

[0057] In some specific embodiments, the feeding slider 230 is provided with a plurality of positioning parts 240, which are arranged sequentially along the length direction of the guide rail 210. This allows the feeding slider 230 to continuously adjust multiple swing arms 200 after the swing arms 200 to be adjusted are installed, reducing the frequency of device shutdown for installing the swing arms 200 to be adjusted and improving efficiency.

[0058] In some specific embodiments, the feeding assembly 220 includes a drive motor 290 and a timing belt 300. The timing belt 300 is used for transmission between the drive motor 290 and the feeding slider 230. The drive motor 290 is used to drive the feeding slider 230 to slide. Thus, by using the drive motor 290 and the timing belt 300 to drive the movement of the feeding slider 230, the movement position of the feeding slider 230 can be made more precise.

[0059] In some specific embodiments, there are two feeding components 220, and the two feeding components 220 alternately feed the swing arm 200 to be adjusted onto and off the device.

[0060] Understandably, when one feeding assembly 220 is adjusting the spring 140, the adjusted swing arm 200 and the new swing arm 200 can be disassembled and installed on the other feeding assembly 220 at the same time. Thus, the two feeding assemblies 220 can adjust the spring 140 and disassemble and install the swing arm 200 at the same time, eliminating the need to stop the machine to disassemble and install the swing arm 200, thereby improving the working efficiency of the adjustment device.

[0061] Reference Figure 6 Furthermore, one feeding assembly 220 has a feeding slider 230 equipped with an anti-collision baffle 310, and the other feeding assembly 220 has a feeding slider 230 equipped with an anti-collision photoelectric switch 320. The anti-collision baffle 310 and the anti-collision photoelectric switch 320 cooperate to sense and limit the movement to prevent the two feeding sliders 230 from colliding.

[0062] Understandably, before the two feeding sliders 230 collide, the anti-collision baffle 310 and the anti-collision photoelectric switch 320 sense each other and control the two feeding sliders 230 to stop moving to prevent the two feeding sliders 230 from colliding, thereby avoiding damage to the two feeding sliders 230 from colliding with each other.

[0063] In some specific embodiments, the guide rail 210 is provided with a left limit photoelectric switch 330 and a right limit photoelectric switch 340, and the feeding slider 230 is provided with a limit baffle 350. The left limit photoelectric switch 330 and the right limit photoelectric switch 340 cooperate with the limit baffle 350 to sense and limit the maximum sliding position of the feeding slider 230.

[0064] It is understandable that by using the left limit photoelectric switch 330 and the right limit photoelectric switch 340 in conjunction with the limit baffle 350 to sense and limit the maximum sliding position of the feeding slider 230, it is possible to prevent the feeding slider 230 from sliding beyond the maximum sliding position and interfering with or colliding with other components, thus preventing damage.

[0065] In some specific embodiments, the guide rail 210 is provided with an origin photoelectric switch 360, and the feeding slider 230 is provided with a limit stop 350. The origin photoelectric switch 360 and the limit stop 350 work together to sense and locate the origin position of the feeding slider 230.

[0066] Understandably, when the program is started, the feeding slider 230 needs to be set to the coordinate origin sequentially from the origin photoelectric switch 360 to ensure that the same coordinate position of the feeding slider 230 can be maintained each time it is restarted.

[0067] Reference Figure 3 , Figure 7 and Figure 8 For the measurement adjustment mechanism 250, there are two measurement adjustment mechanisms 250. The two measurement adjustment mechanisms 250 are symmetrically arranged along the guide rail 210. The two measurement adjustment mechanisms 250 are used to adjust the springs 140 of the two swing arm suction nozzle assemblies 110 of the swing arm 200 to be adjusted.

[0068] Understandably, when the feeding slider 230 moves the swing arm 200 to be adjusted to the measurement and adjustment station, the two measurement and adjustment can simultaneously adjust the springs 140 of the two swing arm suction nozzle assemblies 110 of the swing arm 200 to be adjusted, which is beneficial to improving the adjustment efficiency.

[0069] Specifically, the measurement and adjustment mechanism 250 includes a displacement measuring head 260, an adjustment block 270, an adjustment motor 280, and an adjustment control module. The displacement measuring head 260 is used to detect the position of the first swing arm 120 of the swing arm 200 to be adjusted. The adjustment motor 280 is used to drive the adjustment block 270 to push the first swing arm 120 to adjust the spring 140. The adjustment control module is used to receive the measurement information from the displacement measuring head 260 and the motion data from the adjustment motor 280, calculate the adjustment amount of the spring 140, and control the adjustment motor 280 to adjust the spring 140 according to the adjustment amount of the spring 140.

[0070] Understandably, the displacement measuring head 260 measures the position of the first swing arm 120 to detect the deformation of the spring piece 140. Then, the adjustment control module calculates the adjustment amount of the spring piece 140 based on the measurement data from the displacement measuring head 260 and the motion data from the adjustment motor 280, and controls the adjustment motor 280 to adjust the spring piece 140 according to the adjustment amount. Thus, the deformation of the spring piece 140 is automatically detected and the spring piece 140 is automatically adjusted, thereby improving the adjustment efficiency of the spring piece 140.

[0071] In some specific embodiments, the adjusting block 270 is provided with an opening groove 370 on the left or right side. The opening groove 370 accommodates the first swing arm 120 of the swing arm 200 to be adjusted. The front and rear sides of the opening groove 370 abut against the first swing arm 120 respectively and push the first swing arm 120 back and forth.

[0072] Understandably, the opening slot 370 has an opening that allows the first swing arm 120 to enter the opening slot 370, and the opening slot 370, using its front and rear side walls, can abut and push the first swing arm 120 when the adjusting block 270 moves forward and backward.

[0073] In some specific embodiments, the measuring and adjusting mechanism 250 further includes a support frame 380, a lifting frame 390, a translation frame 400, and a mounting frame 410. The lifting frame 390 is slidably mounted on the support frame 380, the translation frame 400 is slidably mounted on the lifting frame 390, and the mounting frame 410 is slidably mounted on the translation frame 400. The adjusting block 270 is mounted on the mounting frame 410, and the adjusting motor 280 is mounted on the translation frame 400. The adjusting motor 280 drives the mounting frame 410 to move back and forth, thereby causing the adjusting block 270 to move back and forth. Thus, the adjusting block 270 can change its height, left and right, and front and back positions through the cooperation of the lifting frame 390, the translation frame 400, and the mounting frame 410. In this way, the position of the adjusting block 270 can be adapted to the position of the swing arm 200 to be adjusted on the feeding slider 230.

[0074] Reference Figure 7 and Figure 9 Furthermore, a first adjusting knob 420 is threaded onto the support frame 380. The first adjusting knob 420 is used to abut against the lifting frame 390 to adjust and position the height of the lifting frame 390. A second adjusting knob 430 is threaded onto the lifting frame 390. The second adjusting knob 430 is used to abut against the translation frame 400 to adjust and position the left and right of the translation frame 400. Thus, the first adjusting knob 420 is used to position the height of the lifting frame 390, and the second adjusting knob 430 is used to position the left and right of the translation frame 400, thereby making the adjustment of the height and left and right positions of the adjusting block 270 more accurate.

[0075] Furthermore, a first bolt is provided between the support frame 380 and the lifting frame 390. The support frame 380 has a first waist hole extending vertically, and the lifting frame 390 has a first threaded hole. The first bolt passes through the first waist hole and is threaded into the first threaded hole to fix the support frame 380 and the lifting frame 390. A second bolt is provided between the lifting frame 390 and the translation frame 400. The lifting frame 390 has a second waist hole extending horizontally, and the translation frame 400 has a second threaded hole. The second bolt passes through the second waist hole and is threaded into the second threaded hole to fix the support frame 380 and the lifting frame 390. The lifting frame 390 and the translation frame 400 are fixed together, so that the first waist hole allows the first bolt to move up and down to adapt to the height adjustment of the lifting frame 390 relative to the support frame 380. At the same time, the first bolt fixes the support frame 380 and the lifting frame, making the position of the lifting frame 390 more stable. In addition, the second waist hole allows the second bolt to move left and right to adapt to the left and right position adjustment of the translation frame 400 relative to the lifting frame 390. At the same time, the second bolt fixes the lifting frame 390 and the translation frame 400, making the position of the translation frame 400 more stable.

[0076] In some specific embodiments, a first screw is provided between the translation frame 400 and the mounting frame 410. The first screw is rotatably connected to the translation frame 400 and threadedly connected to the mounting frame 410. The adjusting motor 280 is used to drive the first screw to rotate, so that the first screw can transmit power between the adjusting motor 280 and the mounting frame 410, thereby enabling the adjusting motor 280 to accurately drive the mounting frame 410 to move.
