[0003] In the related art, the optoelectronic parameter testing equipment of the chip has a swing arm and a testing platform. The testing platform is a rotating disk. A loading position, a posture detection position, an adjustment position and a testing position are arranged in sequence around the circumferential direction of the rotating disk. Each station is fixed and does not move with the rotation of the rotating disk. After the swing arm loads the grain to the loading position, the rotating disk rotates the grain at the loading position to the posture detection position to detect the posture of the grain. After the detection, the rotating disk continues to rotate to the adjustment position to adjust the posture of the grain. The grain needs to be adjusted at multiple stations, which increases the complexity of the equipment and increases the equipment cost. Utility Model Content

[0043] Reference Figures 1 to 7 As shown, the embodiment of the utility model proposes a testing device, including: a loading and unloading device 100, a transfer device 200 and a detection device 300, the loading and unloading device 100 includes a planar moving member 110 capable of moving in a moving plane, a rotating member 120 connected to the planar moving member 110 and capable of rotating around an axis in a first direction, and a fixing component 130 connected to the rotating member 120, the first direction is perpendicular to the moving plane, the fixing component 130 is used to fix a material tray 140, the material tray 140 has a placement surface 141 for placing grains, and the placement surface 141 is parallel to the moving plane; the transfer device 200 has a transfer component 210 for fixing and transferring grains; the detection device 300 is used to detect the first actual posture of the transfer component 210, and the placement surface 141 1, and / or, for detecting the third actual posture of the grain fixed by the transfer component 210, and the fourth actual posture of the grain placement position on the placement surface 141; wherein the fixing component 130 is configured as follows: when the grain is loaded, when the detection device 300 detects the first actual posture and the second actual posture, it is driven by the rotating member 120 and the plane moving member 110 according to the first actual posture and the second actual posture to adjust the second actual posture to align with the first actual posture; and / or, when the grain is unloaded, when the detection device 300 detects the third actual posture and the fourth actual posture, it is driven by the rotating member 120 and the plane moving member 110 according to the third actual posture and the fourth actual posture to adjust the fourth actual posture to align with the third actual posture. The test equipment in this embodiment can adjust the placement posture of the grain in the loading device and / or the unloading device, and the integrated station is in the loading and unloading device 100 to improve the detection efficiency.

[0044] In this embodiment, the loading and unloading device 100 includes a loading device and / or a unloading device. Figure 1 and Figure 2 The loading and unloading device 100 can be a loading device or a unloading device.

[0045] Among them, refer to Figure 1As shown, the loading and unloading device 100 includes a second moving member capable of moving along a second direction and a third moving member capable of moving along a third direction, the second direction is perpendicular to the third direction, and the second direction and the third direction form a moving plane. In this embodiment, the second direction is a horizontal direction, the third direction is a vertical direction, the third moving member is transmission-connected to the second moving member, the third moving member forms a plane moving member 110, and the rotating member 120 is connected to the third moving member. Specifically, the specific transmission structure of the second moving member moving along the second direction can be a screw slider structure, a pulley transmission structure, a pneumatic transmission structure, a hydraulic transmission structure or an electromagnetic transmission structure; the specific transmission structure of the third moving member moving along the third direction can be a screw slider structure, a pulley transmission structure, a pneumatic transmission structure, a hydraulic transmission structure or an electromagnetic transmission structure.

[0046] Reference Figure 1 As shown, the outer contour shape of the material tray 140 is a circular disk with four rectangular edges cut out, and the four rectangular edges refer to the extension lines of the four edges forming a rectangle. The fixing assembly 130 includes a bottom support plate and two clamping assemblies opposite to each other along the second direction, and the clamping assembly includes a first clamping plate and a second clamping plate opposite to each other along the first direction. A clamping cavity is formed between the first clamping plate and the second clamping plate for clamping one side of the material tray 140. The two opposite clamping assemblies clamp the rectangular edges on both sides of the material tray 140 respectively, and the bottom support plate supports the rectangular edge of the bottom of the material tray 140. In addition, an adhesive film for bonding the grains is provided on the material tray 140, and the adhesive film is a UV film or a blue film. In this embodiment, the adhesive film is a blue film, and the grains are arranged in the horizontal and vertical directions and bonded to the blue film, so the material tray 140 can be placed vertically without causing the grains to fall.

[0047] Reference Figure 2 and Figure 7 As shown, the transfer device 200 includes a transfer drive 220 that is transmission-connected to the transfer component 210. The transfer drive 220 is used to drive the transfer component 210 to move between the test surface 410 and the placement surface 141. The drive mode of the transfer drive 220 can be rotation or linear reciprocating movement. For example, when the test surface 410 and the placement surface 141 are both placed horizontally, the transfer drive 220 includes a transfer arm and a motor, and the motor drives the transfer arm to rotate in the horizontal plane, and the transfer arm can move to the test surface 410 or the placement surface 141. The transfer drive 220 can also be a motor, a lead screw and a slider, the lead screw passes through the test surface 410 and the placement surface 141, and the motor drives the lead screw to rotate, thereby causing the slider to reciprocate between the test surface 410 and the placement surface 141; and when the test surface 410 and the placement surface 141 are placed vertically, the transfer drive 220 includes a transfer arm and a motor, and the motor drives the transfer arm to rotate in the vertical plane, and the transfer arm can move to the test surface 410 or the placement surface 141.

[0048] Specifically, during the grain loading process, the detection device 300 detects the first actual posture of the transfer component 210 to obtain the posture of the grain after the transfer component 210 adsorbs the grain. The detection device 300 detects the second actual posture of the grain on the placement surface 141. When there is an offset angle value, the rotating member 120 drives the fixed component 130 to rotate so that the grain contour on the placement surface 141 is parallel to the contour of the grain to be adsorbed by the transfer component 210. The detection device 300 then detects the planar offset between the grain on the placement surface 141 and the grain contour to be adsorbed by the transfer component 210. The planar moving member 110 adjusts the grain on the placement surface 141 to be aligned with the transfer component 210. The transfer component 210 adsorbs the grain on the placement surface 141. After the grain is calibrated, its relative position with the transfer component 210 is fixed, and the position accuracy of the grain is fixed. After unloading, it can be directly processed or tested, which improves detection efficiency and saves space occupied by multiple workstations, thereby simplifying the equipment and reducing equipment costs.

[0049] In addition, an ejector rod is provided on the back side of the blue film on the material tray 140 to eject the grains on the blue film. The transfer component 210 absorbs the grains ejected by the ejector rod and tears the grains off the blue film through negative pressure absorption force, thereby separating the grains from the blue film. After the grains are torn off, the ejector rod retreats and the blue film returns to its original state. The planar moving part 110 of the loading device adjusts the next grain on the placement surface 141 to be aligned with the transfer component 210, and the ejector rod makes it easier for the transfer component 210 to absorb the grains.

[0050] During the grain unloading process, first, the detection device 300 detects the offset angle value between the third actual posture of the grain fixed by the transfer component 210 and the fourth actual posture of the grain placement position on the placement surface 141, and the rotating member 120 drives the fixed component 130 to rotate the offset angle value, so that the outline of the grain fixed by the transfer component 210 is parallel to the outline of the grain placement position. Secondly, the detection device 300 detects the offset amount of the grain fixed by the transfer component 210 and the grain placement position in the moving plane, and the plane moving member 110 drives the fixed component 130 to move the corresponding offset amount in the moving plane, so that the third actual posture is aligned with the fourth actual posture. Finally, the grain fixed by the transfer component 210 is aligned and placed in the grain placement position on the placement surface 141. After the grains are calibrated, each grain is neatly arranged in the horizontal and vertical directions on the placement surface 141, which is convenient for subsequent processing and production, while also saving the space occupied by multiple workstations, which simplifies the equipment and reduces the equipment cost.

[0051] The offset in the plane detected by the detection device 300 refers to: the distance between the grain adsorbed by the transfer component 210 and the grain placement position of the placement surface 141 along the second direction; the distance between the grain adsorbed by the transfer component 210 and the grain placement position of the placement surface 141 along the third direction, and then the plane moving member 110 is driven to move along the second direction and the third direction to align the grain and the grain placement position in the moving plane. In this embodiment, the detection device 300 is a visual shooting member, such as a CCD camera.

[0052] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, in some specific embodiments of the present invention, the loading and unloading device 100 also includes a fixed plate 121, a rotating plate 122 rotatably connected to the fixed plate 121, and a driving assembly connected to the fixed plate 121, the fixed plate 121 is connected to the planar moving part 110, and the driving assembly is transmission-connected to the rotating plate 122 to drive the rotating plate 122 to rotate around the first direction.

[0053] The rotating plate 122 includes a first rotating part and a second rotating part connected in sequence along a first direction, the first rotating part is rotatably connected to the fixed plate 121, the driving assembly includes a driving member 124, a transmission wheel connected to the driving member 124, and a transmission belt 123 connected to the transmission wheel and the second rotating part, and the driving member 124 is connected to the fixed plate 121.

[0054] Specifically, the fixed plate 121 is in the shape of a plate, and a circular through hole is provided on the fixed plate 121. The rotating plate 122 is cylindrical or stepped cylindrical as a whole. In the present embodiment, the rotating plate 122 is in the shape of a stepped cylinder, and the first rotating part and the second rotating part are both cylindrical and coaxially arranged. The diameter of the first rotating part is smaller than the diameter of the second rotating part. The outer circumference of the first rotating part is rotatably connected to the inner circumference of the circular through hole of the fixed plate 121 through a rotating bearing so as to rotate relative to the fixed plate 121 through the rotating bearing. The outer circumference of the second rotating part is connected to the transmission belt 123. The transmission belt 123 squeezes the outer circumference of the second rotating part through its own tension, thereby generating friction, so that the transmission belt 123 can drive the second rotating part and the first rotating part to rotate together; the transmission belt 123 maintains its own tension through the transmission wheel, and the driving member 124 includes a driving wheel and a motor. The outer circumference of the driving wheel also tightens the transmission belt 123, and the motor drives the driving wheel to rotate, thereby driving the transmission belt 123 to rotate.

[0055] Reference Figure 4As shown, in some specific embodiments of the present utility model, the rotating plate 122 is provided with a first detection portion 1221, the maximum arc stroke of the first detection portion 1221 rotating in the rotation direction is L1, the preset arc length of the first detection portion 1221 in the rotation direction is L2, the fixed plate 121 is provided with a first detection member 1211 capable of rotating through the first detection portion 1221, one end of the first detection portion 1221 in the rotation direction is aligned with the first detection member 1211, the arc length from the alignment position of the first detection portion 1221 to the end face of one end is L3, and the upper The unloading device 100 satisfies: L2≥L1+L3; the first detection part 1221 is configured as follows: when one end is aligned with the first detection member 1211, the rotating plate 122 is in an initial position; when the rotating plate 122 rotates and the first detection part 1221 continuously triggers the first detection member 1211, the rotation direction of the rotating plate 122 is a forward rotation direction; when the rotating plate 122 rotates and the first detection part 1221 changes from triggering the first detection member 1211 to not continuously triggering the first detection member 1211, the rotation direction of the rotating plate 122 is a reverse rotation direction.

[0056] It is worth understanding that the rotation direction of the rotating plate 122 is determined by whether the first detection unit 1221 continuously triggers the first detection member 1211. At the same time, the zero position of the rotating plate 122 is determined by the alignment position of the first detection unit 1221 and the first detection member 1211, which facilitates subsequent detection and improves detection accuracy.

[0057] In this embodiment, the first detection member 1211 is a photoelectric switch, and the first detection portion 1221 is an arc-shaped baffle, and the arc length of the arc-shaped baffle is L2. In the initial position, one end of the first detection portion 1221 along the circumferential direction is located in the photoelectric switch and triggers the photoelectric switch. When the first detection member 1211 rotates toward the other end in the circumferential direction, the first detection portion 1221 will continue to touch the first detection member 1211, that is, the arc-shaped baffle continues to block the detection light in the photoelectric switch; and when the first detection member 1211 rotates along the other end away from the circumferential direction, the first detection portion 1221 will be separated from the first detection member 1211, so that the first detection member 1211 quickly changes from a triggered state to an untriggered state, that is, the arc-shaped baffle is separated from the photoelectric switch and no longer blocks the detection light in the photoelectric switch, thereby determining the rotation direction of the rotating member 120 to determine the rotation direction of the grains on the material tray 140. Among them, because one end of the first detection part 1221 is aligned with the first detection member 1211, the length of L3 accounts for a relatively low proportion of the overall arc length L2 of the arc-shaped baffle, so that when the first detection part 1221 rotates along the other end away from the circumferential direction, it can quickly disengage from the first detection member 1211 to change the trigger state of the first detection member 1211.

[0058] Reference Figure 3 and Figure 5As shown, in some specific embodiments of the present invention, the loading and unloading device 100 also includes a first movable member 150 capable of moving along a first direction, and the first movable member 150 is connected to the rotating member 120 so as to rotate with the rotating member 120. The first movable member 150 is used to eject the adhesive film in the material tray 140 along the first direction, and the adhesive film is used to bond the grains.

[0059] It is worth to understand that, during the unloading process, the first moving member 150 pushes out the adhesive film in the material tray 140 along the first direction, and the transfer component 210 can better transfer the grains to the surface of the adhesive film.

[0060] Specifically, the rotating member 120 is provided with a mounting through hole along its axial direction, and the first moving member 150 is provided in the mounting through hole. The first moving member 150 is in the shape of a disk. After the first moving member 150 contacts the adhesive film, it pushes out the adhesive film in a circular area, and the die is bonded to the adhesive film in the circular area. The surface of the first moving member 150 is provided with a plurality of adsorption holes to stably adsorb the adhesive film, so as to prevent the adhesive film from shifting relative to the first moving member 150, resulting in the dislocation of the die position.

[0061] Reference Figure 1 , Figure 3 and Figure 5 As shown, in some specific embodiments of the present invention, the loading and unloading device 100 also includes a first transmission assembly 160 that is transmission-connected to the first moving member 150, and the first transmission assembly 160 includes a first fixed frame 161 connected to the rotating member 120, a first driving source 162 connected to the first fixed frame 161, a cam 163 transmission-connected to the first driving source 162, and an elastic reset member connecting the first fixed frame 161 and the first moving member 150, along the first direction, the outer peripheral surface of the cam 163 abuts against the first moving member 150; the first driving source 162 is configured to: drive the cam 163 to rotate, when the cam 163 rotates in the direction of increasing rotation radius, the outer peripheral surface of the cam 163 abuts against the first moving member 150, and drives the first moving member 150 to extend, the elastic reset member undergoes elastic deformation, and increases elastic potential energy; when the cam 163 rotates in the direction of decreasing rotation radius, the elastic reset member releases at least part of the elastic potential energy to drive the first moving member 150 to retreat and abut against the outer peripheral surface of the cam 163.

[0062] It is worth understanding that the cam 163 is used to drive the first movable member 150 to extend in the first direction, thereby improving the moving accuracy of the first movable member 150 and the abutment accuracy between the first movable member 150 and the adhesive film. The first driving source 162 is rotated to control the abutment between the outer peripheral surface of the cam 163 and the first movable member 150, making the control more convenient.

[0063] Specifically, the cam 163 has different rotational radii. When the different rotational radii of the cam 163 abut against the outer peripheral surface of the first moving member 150, the first moving member 150 will be in different positions, thereby realizing the extension of the first moving member 150. When the cam 163 does not push out the first moving member 150, the elastic reset member also has a certain elastic potential energy, through which the first moving member 150 is always abutted against the outer peripheral surface of the cam 163. When the cam 163 begins to push out the first moving member 150, the elastic potential energy of the elastic reset member is further improved on the original basis, thereby also applying an elastic reverse force to the cam 163, so that the outer peripheral surface of the cam 163 and the first moving member 150 abut more closely.

[0064] In this embodiment, the first moving member 150 is provided with an auxiliary wheel 151, which is coaxially arranged with the cam 163, and the outer circumference of the auxiliary wheel 151 abuts against the outer circumference of the cam 163. When the cam 163 rotates, the auxiliary wheel 151 also rotates driven by the cam 163, thereby reducing the wear of the outer circumference of the cam 163.

[0065] Reference Figure 5 As shown, in some specific embodiments of the present invention, the cam 163 is provided with a second detection portion 1631, the first fixing frame 161 is provided with a second detection member 1611, the second detection portion 1631 is provided in the moving path of the second detection member 1611, and the second detection portion 1631 is configured to: when the first moving member 150 is extended to a preset extended position, it is detected by the second detection member 1611, and the first moving member 150 stops moving;

[0066] And / or, the first fixed frame 161 is provided with a third detection member, the second detection portion 1631 is provided in the moving path of the third detection member, and the second detection portion 1631 is configured to be detected by the third detection member when the first movable member 150 retreats to the initial position, and the first movable member 150 stops moving.

[0067] It is worth understanding that the rotation position of the cam 163 is detected by the second detection part 1631 and the second detection member 1611 to prevent the first movable member 150 from exceeding the limit extension position, causing the adhesive film to be ejected too much and damaged by excessive tension; the rotation position of the cam 163 is detected by the second detection part 1631 and the third detection member to stop the first movable member 150 at the initial position, so as to facilitate the correction and zeroing of the initial position of the first movable member 150 and improve the movement accuracy of the first movable member 150.

[0070] It is worth understanding that the test surface 410 and the placement surface 141 are set at a preset angle α, which can reduce the floor space of the test device 400 and the loading and unloading device 100, thereby reducing the equipment's footprint, making the overall layout of the equipment more compact and more convenient to use.

The test surface 410 is provided with a plurality of stations in sequence around the circumferential direction of the test disk, each station is provided with corresponding equipment, and each station is fixedly set. When the test disk rotates, the conveyed grains are passed through each station in sequence and corresponding actions are performed at the station; for example, the test disk is provided with a loading station, a testing station and an unloading station, and the loading transfer device 200 moves the grains on the loading device tray 140 to the loading station of the test disk; then the test disk rotates, and the grains at the loading station are rotated to the testing station for testing; after the test, the test disk rotates again, and the grains at the testing station are rotated to the unloading station, and the unloading transfer device 200 transfers the grains at the unloading station of the test platform to the tray 140 of the unloading device. It should be noted that the actual testing device 400 also includes a die positioning station and the like.

[0073] It is worth understanding that by changing the optical path within the outer frame 310, the main lens can observe the first observation section 311 and the second observation section 312 respectively, and a single main lens can detect the test surface 410 and the placement surface 141, saving the number of main lenses and saving costs.

The shielding drive source 321 is a telescopic air cylinder or a telescopic oil cylinder or a lead screw slider structure or an electromagnetic linear guide rail or other structure with a linear stroke, as long as the shielding drive source 321 can drive the shielding member 322 along the second direction.
