[0046] Reference Figures 1-4The utility model embodiment's carrier positioning device includes bearing plate 1, first clamping block structure 31, second clamping block structure 32, third clamping block structure 33, fourth clamping block structure 34 and transmission structure 2. Bearing plate 1 is used to place the carrier to be handled, and provides support for the installation of other positioning structures. First clamping block structure 31 and second clamping block structure 32 preliminarily position the carrier on bearing plate 1, avoid its position to appear too much deviation, and compensate according to the shape and size of different carriers. Third clamping block structure 33 and fourth clamping block structure 34 are driven by transmission structure 2, and further position the carrier after preliminary positioning. Meanwhile, the drive assembly 7 of transmission structure 2 is arranged outside bearing plate 1, which avoids the occupation of the drive assembly 7 to the installation space on bearing plate 1, and the carrier positioning device can add other structures, such as sensors, on bearing plate 1 according to actual needs, so as to facilitate the connection with other processes.

[0047] Referring to Figure 1 、 Figure 2 、 Figure 3 , bearing plate 1 is provided with first sliding groove 111 and second sliding groove 112, and the bottom surface of bearing plate 1 is provided with accommodating groove 12, and first sliding groove 111 and second sliding groove 112 are communicated with accommodating groove 12 respectively. First sliding groove 111 and second sliding groove 112 are used to accommodate third clamping block structure 33 and fourth clamping block structure 34 and limit the sliding direction thereof. A part of transmission structure 2 is arranged in accommodating groove 12, first sliding groove 111 and second sliding groove 112 are communicated with accommodating groove 12, so that transmission structure 2 can drive third clamping block structure 33 and fourth clamping block structure 34 to position the carrier at the same time, and drive assembly 7 can be arranged outside bearing plate 1, avoiding the occupation of the installation space, so that bearing plate 1 can add other structures according to actual conditions.

[0048] Referring to Figure 1 、 Figure 2 , first clamping block structure 31 and second clamping block structure 32 are arranged on the top surface of bearing plate 1 and are used for preliminarily positioning the carrier. First clamping block structure 31 is arranged on one side of bearing plate 1 along the length direction, second clamping block structure 32 is arranged on one side of bearing plate 1 along the width direction, and first clamping block structure 31 and second clamping block structure 32 are limited in the x-axis and y-axis directions.

[0049] Among them, such as Figures 1-2 、 Figure 7As shown, the first clamping block structure 31 comprises a first fixing member 311, at least one first elastic block 312 and at least one first elastic member, the first fixing member 311 is provided with at least one first elastic groove, the first elastic member is arranged in the first elastic groove, and the two ends of each first elastic member are connected to the first fixing member 311 and one first elastic block 312. That is, the number of the first elastic groove, the first elastic member and the first elastic block 312 is the same, and each first elastic groove can accommodate one first elastic member and one first elastic block 312. According to actual conditions, the number of the first elastic groove, the first elastic member and the first elastic block 312 can be one, two or more. The first fixing member 311 can provide fixed positioning, the first elastic block 312 is compressed into the corresponding first elastic groove when it is under pressure, and the first elastic block 312 is pushed out of the first fixing member 311 by the first elastic member when it is not under pressure, so that the first clamping block structure 31 can realize certain compensation when positioning the carrier. That is, when the size of the carrier is small, the first elastic block 312 that is stretched out can compensate for the size of this part; when the size of the carrier is large, the first elastic block 312 that is stretched out can be compressed into the first elastic groove in the subsequent positioning process, reducing the positioning error.

[0050] Referring to Figures 1-2 , Figure 7 , the second clamping block structure 32 also comprises a second fixing member 321, at least one second elastic block 322 and at least one second elastic member, which limits the carrier in the horizontal direction in the direction perpendicular to the first clamping block structure 31 in the horizontal plane, for example, when the first clamping block structure 31 limits the position of the carrier in the x-axis direction, the second clamping block structure 32 limits the position of the carrier in the y-axis direction. The second fixing member 321 is provided with at least one second elastic groove, and the second elastic member is arranged in the second elastic groove, and the two ends of each second elastic member are connected to the second fixing member 321 and one second elastic block 322, and the second elastic block 322 is compressed into the corresponding second elastic groove when it is under pressure. The number of the second elastic groove, the second elastic member and the second elastic block 322 is the same, according to actual conditions, the number of the second elastic groove, the second elastic member and the second elastic block 322 can be one, two or more. When the size of the carrier is small, the second elastic block 322 that is stretched out can compensate for the size of this part; when the size of the carrier is large, the second elastic block 322 that is stretched out can be compressed into the second elastic groove in the subsequent positioning process, reducing the positioning error.

[0051] Referring to Figures 4-5The transmission structure 2 comprises a driving assembly 7, a transmission member 21, a first transmission rod 22 and a second transmission rod 23. The driving assembly 7 can be a cylinder, a push rod or the like structure, which drives the first transmission rod 22 to move. The middle part of the transmission member 21 is rotatably arranged in the accommodating groove 12. According to actual conditions, the rotation of the transmission member 21 can be realized by a pin column or the like structure. The transmission member 21 can be U-shaped or V-shaped, which is used to convert the linear motion from the first transmission rod 22 into linear motion perpendicular to the motion direction and drive the second transmission rod 23 to move. One end of the first transmission rod 22 is connected with one end of the transmission member 21, and the other end extends out of the first sliding groove 111 and is connected with the driving assembly 7. That is, the first transmission rod 22 is driven by the driving assembly 7 to move and drive the transmission member 21 to rotate. One end of the second transmission rod 23 is connected with the other end of the transmission member 21, and the other end extends into the second sliding groove 112. That is, the second transmission rod 23 is pushed by the transmission member 21 to slide, and the sliding directions of the first transmission rod 22 and the second transmission rod 23 are perpendicular to each other. The system formed by the first transmission rod 22, the transmission member 21 and the second transmission rod 23 can provide the sliding effect of two perpendicular directions which can be synchronously contracted and expanded when only driven from one direction. At the same time, since the first transmission rod 22 and the second transmission rod 23 can move in two perpendicular directions by applying driving in one direction, the driving assembly 7 can be arranged outside the bearing plate 1, and does not need to be arranged in the middle of the bearing plate 1 to occupy most of the space.

[0052] In some embodiments, with reference to Figure 5 、 Figure 6 The first transmission rod 22 is provided with a first movable groove 24 at the end connected with the transmission member 21, the second transmission rod 23 is provided with a second movable groove 25 at the end connected with the transmission member 21, and the two ends of the transmission member 21 are connected in the first movable groove 24 and the second movable groove 25 through connecting columns. The connecting columns protrude from the two ends of the transmission member 21 and are used to movably connect with the first transmission rod 22 and the second transmission rod 23. The first movable groove 24 and the second movable groove 25 are used to realize the buffering in the transmission process and limit the movable tracks between the transmission member 21 and the first transmission rod 22 and the second transmission rod 23. The first movable groove 24 and the second movable groove 25 are matched with the first sliding groove 111 and the second sliding groove 112, and finally realize the effect that the movement tracks of the first transmission rod 22 and the second transmission rod 23 are perpendicular to each other. At this time, the third clamping block structure 33 and the fourth clamping block structure 34 are driven by the first transmission rod 22 and the second transmission rod 23 to move in the perpendicular directions, and are matched with the first clamping block structure 31 and the second clamping block structure 32 to position the carrier on the bearing plate 1, thereby limiting the carrier from multiple directions and increasing the positioning accuracy.

[0053] In some embodiments, as Figure 4As shown, the receiving groove 12 defines a first transmission groove 13 and a second transmission groove 14 for accommodating the first transmission rod 22 and the second transmission rod 23 and providing position limits for their movement. The first transmission groove 13 and the second transmission groove 14 extend perpendicularly to each other. When the transmission structure 2 is in operation, the first transmission rod 22 slides within the first transmission groove 13, and the second transmission rod 23 slides within the second transmission groove 14, further increasing positioning accuracy.

[0054] Reference Figure 1 、 Figures 4-6 , the third clamping block structure 33 is slidably set in the first sliding groove 111 and is opposite to the first clamping block structure 31, forming an effective positioning of the carrier on the horizontal plane x-axis. The third clamping block structure 33 is connected to the first transmission rod 22. When the first transmission rod 22 is driven by the driving component 7 to move, the third clamping block also moves therewith. The fourth clamping block structure 34 is slidably set in the second sliding groove 112 and is opposite to the second clamping block structure 32, forming an effective positioning of the carrier on the horizontal plane y-axis. The fourth clamping block structure 34 is connected to the second transmission rod 23. When the second transmission rod 23 is driven by the transmission member 21 to move, the fourth clamping block structure 34 also moves therewith. The moving directions of the third clamping block structure 33 and the fourth clamping block structure 34 are perpendicular, and form positioning of the carrier in four directions on the horizontal plane together with the first clamping block structure 31 and the second clamping block structure 32, which can improve positioning accuracy and product yield.

[0055] Specifically, refer to Figures 4-6 The third clamping block structure 33 includes a first clamping block 331 and a first limiting block 332, wherein the first clamping block 331 is connected to the top of the first limiting block 332 and extends above the top surface of the carrier 1, and is used to contact and position the carrier, and the first limiting block 332 is used to follow the movement of the transmission structure 2 to drive the first clamping block 331 to achieve its movement. The first limiting block 332 is located in the first sliding groove 111 and is connected to the first transmission rod 22. The first transmission rod 22 drives the first clamping block 331 to move through the first limiting block 332. In other words, when the first transmission rod 22 moves, the first limiting block 332 also moves along the sliding groove, and drives the first clamping block 331 to move to position the carrier. By guiding and limiting the first limiting block 332, the positioning accuracy can be improved.

[0056] Reference Figures 4-6The fourth clamping block structure 34 includes a second clamping block 341 and a second limiting block 342, wherein the second clamping block 341 is connected to the top of the second limiting block 342 and extends above the top surface of the supporting plate 1, and is used to contact and position the carrier, and the second limiting block 342 is used to follow the movement of the transmission structure 2 to drive the second clamping block 341 to achieve its movement. The second limiting block 342 is located in the second sliding groove 112 and is connected to the second transmission rod 23. The second transmission rod 23 drives the second clamping block 341 to move through the second limiting block 342. That is to say, when the second transmission rod 23 moves, the second limiting block 342 also moves along the sliding groove and drives the second clamping block 341 to move to position the carrier. According to actual conditions, the first clamping block 331 and the second clamping block 341 are respectively provided with a first sensor on the side facing the inside of the supporting plate 1, which is used to detect the pressure exerted on the first clamping block 331 and the second clamping block 341.

[0057] During positioning, in order to prevent the first clamping block 331 and the second clamping block 341 from over-pressing the carrier and causing damage to the carrier and electronic components, a first sensor is set to detect the pressure, and different pressure setting values ​​are set for different carrier sizes. Figures 1-2 A lower pressure is set for smaller carriers. When positioning the carrier, the carrier is first positioned by the first clamping block structure 31 and the second clamping block structure 32, and the first elastic block 312 and the second elastic block 322 compensate for the carrier's size. The drive assembly 7 then activates and drives the third clamping block structure 33 and the fourth clamping block structure 34 through the transmission assembly for further positioning. When the first clamping block 331 and the second clamping block 341 contact the carrier and move in alignment, the carrier squeezes the first elastic block 312 and the second elastic block 322, causing them to partially retract into the first and second fixed blocks until the first sensor senses that the force between the first and second clamping blocks 331, 341 and the carrier has reached the set value. At this point, the carrier is positioned to the desired position. For larger carriers, a higher pressure is set. When the first and second clamping blocks 331, 341 contact the carrier and align the carrier, the carrier squeezes the first and second elastic blocks 312, 322, causing them to retract mostly into the first and second fixed blocks until the first sensor detects that the force between the first and second clamping blocks 331, 341, and the carrier has reached the set value. Due to the larger size of the carrier at this time, the first and second elastic blocks 312, 322 retract further, and the elastic force generated by the first and second elastic members is greater. Therefore, the pressure exerted by the carrier on the first and second clamping blocks 331, 341 is greater, requiring a higher setting value to indicate positioning and improve positioning accuracy.

[0058] In some embodiments, reference Figures 4-6The third clamping block structure 33 further comprises a first limiting frame 333 and a third elastic member 334. The first limiting frame 333 is installed at the opening of the first sliding groove 111 near the edge of the bearing plate 1, and is used to limit the movement of the first limiting block 332 to avoid it from falling out of the first sliding groove 111. The third elastic member 334 provides a buffer for the movement of the first limiting block 332. The first limiting frame 333 and the bearing plate 1 form a first moving groove 336, which is used to further guide and limit the movement of the first limiting block 332. The first limiting block 332 has a first moving block 335 protruding on both sides, which slides in the first moving groove 336 to limit its linear movement and avoid it from falling out of the vertical direction. The third elastic member 334 is connected between the first limiting frame 333 and the first limiting block 332 for buffering. When the first limiting block 332 is driven by the first transmission rod 22 to move to the middle of the bearing plate 1, the third elastic member 334 is elongated and provides a pulling force, so that the first limiting block 332 can be pulled back to the initial position quickly after positioning; when the first limiting block 332 is driven to move to the edge of the bearing plate 1, i.e. to one side of the first limiting frame 333, the third elastic member 334 is compressed and provides a spring force, so that the first limiting block 332 will not hit the first limiting frame 333 and cause structural damage.

[0059] With reference to Figures 4-6 , Figures 8-11 wherein Figure 9 is Figure 8 a partial cross-sectional view of the section A-A, showing the structure of the fourth clamping block structure 34; Figure 11 is Figure 10Figure 16 is a partial cross-sectional view of the middle section B-B, showing the structure of the fourth clamp block structure 34 after the second limiting block 342 is removed. The fourth clamp block structure 34 further comprises a second limiting frame 343 and a fourth elastic member 344. The second limiting frame 343 is installed at the opening of the second sliding groove 112 near the edge of the carrier plate 1, and is used to limit the movement of the second limiting block 342 to prevent it from falling out of the second sliding groove 112. The fourth elastic member 344 provides a buffer for the movement of the second limiting block 342. The second limiting frame 343 and the carrier plate 1 form a second movement groove 346, which is used to further guide and limit the movement of the second limiting block 342. The second limiting block 342 has a second movement block 345 protruding on both sides, which slides in the second movement groove 346 to limit its linear motion and prevent the second movement block 345 from falling out of the vertical direction. The fourth elastic member 344 is connected between the second limiting frame 343 and the second limiting block 342 for buffering. When the second limiting block 342 is moved towards the middle of the carrier plate 1 by the second transmission rod 23, the fourth elastic member 344 is elongated and provides a pulling force, so that the second limiting block 342 can be pulled back to the initial position quickly after positioning; when the second limiting block 342 is moved towards the edge of the carrier plate 1, i.e. to the side of the second limiting frame 343, the fourth elastic member 344 is compressed and provides a spring force, so that the second limiting block 342 will not hit the second limiting frame 343 and cause structural damage.

[0060] In some embodiments, referring to Figures 1-3 , the carrier plate 1 is further provided with at least one suction accessory 41 for suction in the vertical direction, i.e. the z-axis direction, of the carrier on the carrier plate 1. According to actual conditions, pre-suction can be performed by the suction accessory 41 before using the third clamp block structure 33 and the fourth clamp block structure 34 for further positioning, to avoid the carrier from falling or bouncing out during positioning due to its thickness or other reasons; or suction for z-axis positioning can be performed after the third clamp block structure 33 and the fourth clamp block structure 34 are positioned. Each suction accessory 41 penetrates the carrier plate 1 and is connected with a suction pipe 42, which is used to connect with an external vacuum pump or other vacuum generating structure to control the suction capacity of the suction accessory 41. The suction accessory 41 is located in the area surrounded by the first clamp block structure 31, the second clamp block structure 32, the third clamp block structure 33 and the fourth clamp block structure 34, and at least one suction accessory 41 can better suction the carrier on the carrier plate 1 to improve the positioning accuracy.

[0061] In some embodiments, referring to Figure 2 , Figures 5-6, the third moving groove 26 is arranged at the end of the first transmission rod 22 away from the transmission member 21, the moving column 71 is arranged at the end of the driving assembly 7, the moving column 71 is arranged in the third moving groove 26, and the driving assembly 7 drives the first transmission rod 22 to move through the moving column 71 and the third moving groove 26. The third moving groove 26 is used for buffering the driving of the driving assembly 7 and guiding the movement of the driving assembly 7 through the moving column 71. For the first transmission rod 22, one end of the first transmission rod 22 is movably connected with the driving assembly 7 through the moving column 71 and the third moving groove 26 and is driven by the driving assembly 7 to slide in the first transmission groove 13, so as to drive the first limiting block 332 connected with the first transmission rod 22 to slide in the first sliding groove 111. Further, the other end of the first transmission rod 22 is movably connected with the transmission member 21 through the connecting rod and the first movable groove 24, and the movement of the first transmission rod 22 drives the transmission member 21 to rotate. For example, when the driving assembly 7 drives the first transmission rod 22 to move inward of the bearing plate 1, the first transmission rod 22 moves along the x-axis direction, drives the transmission member 21 to rotate clockwise from the x-axis direction to the y-axis direction, at this time, the other end of the transmission member 21 away from the first transmission rod 22 is movably connected with the connecting rod and the second transmission rod 23 through the second movable groove 25, the transmission member 21 drives the second movable rod and makes the second movable rod slide along the y-axis direction in the second transmission groove 14 inward of the bearing plate 1. Through the cooperation of the transmission structure 2, the driving assembly 7 can be installed on the external structure of the bearing plate 1, so as to realize the movement of the first clamping block 331 and the second clamping block 341 in two directions by outputting in only one direction, and the space of the bearing plate 1 is effectively avoided.

[0062] With reference to Figures 1-6 When the carrier needs to be positioned, the carrier is first positioned by the first clamping block structure 31 and the second clamping block structure 32. The driving assembly 7 drives the first transmission rod 22 to drive the first limiting block 332 of the third clamping block structure 33 to move in the first sliding groove 111 towards the first clamping block structure 31, at this time, the first moving blocks 335 on both sides of the first limiting block 332 are guided and limited in the first moving groove 336. The first transmission rod 22 drives the transmission member 21 to rotate and drives the second transmission rod 23 to move, the second transmission rod 23 drives the second limiting block 342 of the fourth clamping block structure 34 to move in the second sliding groove 112 towards the second clamping block structure 32, at this time, the second moving blocks 345 on both sides of the second limiting block 342 are guided and limited in the second moving groove 346. The first transmission rod 22 and the second transmission rod 23 slide in the first transmission groove 13 and the second transmission groove 14 which are perpendicular to each other, and drive the first clamping block 331 and the second clamping block 341 to move on the bearing plate 1 through the first limiting block 332 and the second limiting block 342, so as to position the carrier. According to actual conditions, the carrier can be further positioned by the suction member 41 to avoid problems such as inclined sliding when the carrier moves, and the positioning accuracy is improved.

[0063] With reference toFigures 3-4 The accommodation groove 12 is connected with a limiting plate 61 outside, the transmission structure 2 is arranged between the accommodation groove 12 and the limiting plate 61, and the limiting plate 61 is used for protecting the transmission structure 2 from being exposed outside and affecting the accuracy of the transmission process. According to actual conditions, a first detection through groove 15 is arranged in the middle of the bearing plate 1, a second detection through groove 62 is arranged at a position corresponding to the first detection through groove 15 in the limiting plate 61, a transparent plate 63 is arranged on the first detection through groove 15, the first detection through groove 15, the second detection through groove 62 and the transparent plate 63 are in a corresponding position, and are used for exposing the mark information such as a bar code of a carrier placed on the bearing plate 1. A detection assembly 82 is arranged outside the limiting plate 61, the detection assembly 82 corresponds to the position of the second detection through groove 62, and is used for scanning and recording the mark information of the carrier. Figures 1-3 As shown in FIG. 6, at least one second sensor 81 is arranged on the bearing plate 1, and is used for detecting whether the carrier is placed on the bearing plate 1. When it is detected that the carrier is placed on the bearing plate 1, the detection assembly 82 can scan the mark information of the carrier through the transparent plate 63, so as to record and perform the next process flow, and improve the production efficiency.
