Description

[0046] Reference Figure 1-Figure 4The carrier positioning device of the embodiment of the present invention includes a carrier plate 1, a first clamping block structure 31, a second clamping block structure 32, a third clamping block structure 33, a fourth clamping block structure 34 and a transmission structure 2. The carrier plate 1 is used to place the carrier to be processed and provide support for the installation of other positioning structures. The first clamping block structure 31 and the second clamping block structure 32 preliminarily position the carrier on the carrier plate 1 to avoid excessive displacement of its position, and compensate according to the shape and size of different carriers. The third clamping block structure 33 and the fourth clamping block structure 34 are driven by the transmission structure 2 to further position the carrier after the preliminary positioning. At the same time, the driving component 7 of the transmission structure 2 is arranged outside the carrier plate 1, so as to avoid the driving component 7 occupying the installation space on the carrier plate 1. The carrier positioning device can be equipped with other structures on the carrier plate 1 according to actual needs, such as sensors, etc., to facilitate the connection with other processes.

[0047] Reference Figure 1 , Figure 2 , Figure 3 , a first sliding groove 111 and a second sliding groove 112 are provided on the bearing plate 1, and a receiving groove 12 is provided on the bottom surface of the bearing plate 1, and the first sliding groove 111 and the second sliding groove 112 are respectively connected to the receiving groove 12. The first sliding groove 111 and the second sliding groove 112 are used to accommodate the third clamping block structure 33 and the fourth clamping block structure 34 and limit their sliding directions. A part of the transmission structure 2 is arranged in the receiving groove 12, and the first sliding groove 111 and the second sliding groove 112 are connected to the receiving groove 12, so that the transmission structure 2 can simultaneously drive the third clamping block structure 33 and the fourth clamping block structure 34 to position the carrier, and at the same time, the driving component 7 can be arranged outside the bearing plate 1, avoiding its occupation of the installation space, so that the bearing plate 1 can be equipped with other structures according to actual conditions.

[0048] Reference Figure 1 , Figure 2 The first clamping block structure 31 and the second clamping block structure 32 are arranged on the top surface of the carrier plate 1 to perform preliminary positioning of the carrier. The first clamping block structure 31 is arranged on one side of the carrier plate 1 along the length direction, and the second clamping block structure 32 is arranged on one side of the carrier plate 1 along the width direction. The first clamping block structure 31 and the second clamping block structure 32 realize positioning on the x-axis and y-axis in the horizontal direction.

[0049] Among them, Figure 1-Figure 2 , Figure 7As shown, the first clamping block structure 31 includes a first fixing member 311, at least one first elastic block 312 and at least one first elastic member. At least one first elastic groove is provided on the first fixing member 311, and the first elastic member is arranged in the first elastic groove. The first fixing member 311 and a first elastic block 312 are connected at both ends of each first elastic member. In other words, the number of the first elastic grooves, the first elastic members and the first elastic blocks 312 is the same, and each first elastic groove can accommodate a first elastic member and a first elastic block 312. According to actual conditions, the number of the first elastic grooves, the first elastic members and the first elastic blocks 312 can be one, two or more. The first fixing member 311 can provide fixed positioning, and the first elastic block 312 is retracted into the corresponding first elastic groove when it is compressed. When the first elastic block 312 is not compressed, it is pushed by the first elastic member to a part of it extending out of the first fixing member 311, so that the first clamping block structure 31 can achieve certain compensation when positioning the carrier. That is to say, when the carrier size is small, the extended first elastic block 312 can compensate for the size of this part; when the carrier size is large, the extended first elastic block 312 can be compressed into the first elastic groove during the subsequent positioning process to reduce the positioning error.

[0050] Reference Figure 1-Figure 2 , Figure 7 The second clamping block structure 32 also includes 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 a direction perpendicular to the first clamping block structure 31 on 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. At least one second elastic groove is provided on the second fixing member 321, and the second elastic member is arranged in the second elastic groove. The two ends of each second elastic member are connected to the second fixing member 321 and a second elastic block 322. When the second elastic block 322 is compressed, it shrinks into the corresponding second elastic groove. The number of the second elastic groove, the second elastic member and the second elastic block 322 is the same. According to the actual situation, 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 extended second elastic block 322 can compensate for the size of this part; when the size of the carrier is large, the extended second elastic block 322 can be compressed into the second elastic groove in the subsequent positioning process to reduce the positioning error.

[0051] Reference Figure 4-Figure 5The transmission structure 2 includes 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 structure such as a cylinder or a push rod, which drives the first transmission rod 22 to move. The middle part of the transmission member 21 is rotatably arranged in the receiving groove 12. According to actual conditions, the rotation of the transmission member 21 can be realized by a structure such as a pin. 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 a linear motion perpendicular to its motion direction and drive the second transmission rod 23 to move. One end of the first transmission rod 22 is connected to one end of the transmission member 21, and the other end extends from the first sliding groove 111 to be connected to 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 to 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 and slid by the transmission member 21, and the sliding directions of the first transmission rod 22 and the second transmission rod 23 are perpendicular. The system formed by the first transmission rod 22, the transmission member 21 and the second transmission rod 23 can provide two mutually perpendicular sliding effects that can be contracted and opened synchronously when driven from only one direction. At the same time, since the first transmission rod 22 and the second transmission rod 23 can be moved in two perpendicular directions by only applying a drive in one direction, the driving assembly 7 can be arranged outside the carrier plate 1, and does not need to be installed in the middle of the carrier plate 1 to occupy most of the space because it needs to control two directions.

[0052] In some embodiments, reference Figure 5 , Figure 6 The first transmission rod 22 is provided with a first movable groove 24 at one end connected to the transmission member 21, and the second transmission rod 23 is provided with a second movable groove 25 at one end connected to the transmission member 21. The two ends of the transmission member 21 are connected to the first movable groove 24 and the second movable groove 25 respectively through connecting columns. The connecting columns protrude from the two ends of the transmission member 21, and are used to be movably connected 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 achieve buffering during the transmission process, and to limit the movable track between the transmission member 21 and the first transmission rod 22 and the second transmission rod 23, and cooperate with the first sliding groove 111 and the second sliding groove 112 to finally achieve 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 mutually perpendicular directions, and cooperate with the first clamping block structure 31 and the second clamping block structure 32 to position the carrier on the carrier plate 1, and limit the carrier from multiple directions to increase the accuracy of positioning.

[0053] In some embodiments, Figure 4As shown, the receiving groove 12 is provided with 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 a limit for the moving direction thereof. The extending direction of the first transmission groove 13 and the extending direction of the second transmission groove 14 are perpendicular to each other. When the transmission structure 2 is in operation, the first transmission rod 22 slides in the first transmission groove 13 and the second transmission rod 23 slides in the second transmission groove 14, further increasing the accuracy of positioning.

[0054] Reference Figure 1 , Figure 4-Figure 6 , the third clamping block structure 33 is slidably disposed 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 assembly 7 to move, the third clamping block also moves accordingly. The fourth clamping block structure 34 is slidably disposed 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 accordingly. The moving directions of the third clamping block structure 33 and the fourth clamping block structure 34 are perpendicular, and together with the first clamping block structure 31 and the second clamping block structure 32, the positioning of the carrier in four directions on the horizontal plane can be improved. Positioning accuracy and product yield.

[0055] Specifically, refer to Figure 4-Figure 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 plate 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 move. The first limiting block 332 is located in the first sliding groove 111 and is connected to the first transmission rod 22, and 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 Figure 4-Figure 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 carrier 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, and the second transmission rod 23 drives the second clamping block 341 to move through the second limiting block 342. In other words, 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 one side facing the inside of the carrier 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 clamp block 331 and the second clamp block 341 from over-pressing the carrier and causing damage to the carrier and electronic components, a first sensor is provided to detect the pressure, and different pressure setting values ​​are set for different carrier sizes. Figure 1-Figure 2 , a smaller pressure is set for a smaller carrier. 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 size of the carrier. Then the driving assembly 7 is started 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 to partially retract them into the first fixed block and the second fixed block until the first sensor senses that the force between the first clamping block 331, the second clamping block 341 and the carrier reaches the set value, at which time the carrier is positioned to the desired position. A larger pressure is set for a larger carrier. When the first clamp block 331 and the second clamp block 341 contact the carrier and align and move, the carrier squeezes the first elastic block 312 and the second elastic block 322 to make most of them retract into the first fixed block and the second fixed block, until the first sensor senses that the force between the first clamp block 331, the second clamp block 341 and the carrier reaches the set value. Since the carrier is larger at this time, the first elastic block 312 and the second elastic block 322 retract more, and the elastic force generated by the first elastic member and the second elastic member is greater, so the pressure exerted by the carrier on the first clamp block 331 and the second clamp block 341 is greater, and a higher setting value is required to indicate positioning to improve the accuracy of positioning.

[0058] In some embodiments, reference Figure 4-Figure 6The third clamping block structure 33 also includes a first limit frame 333 and a third elastic member 334, wherein the first limit 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 limit block 332 to prevent it from falling out of the first sliding groove 111, and the third elastic member 334 provides a buffer for the movement of the first limit block 332. A first moving groove 336 is formed between the first limit frame 333 and the bearing plate 1, which is used to further guide and limit the movement of the first limit block 332. First moving blocks 335 are protruded on both sides of the first limit block 332, and the first moving block 335 slides in the first moving groove 336, limiting its linear movement and preventing the first moving block 335 from falling off in the vertical direction. The third elastic member 334 is connected between the first limit frame 333 and the first limit block 332 for buffering. When the first limit block 332 is driven by the first transmission rod 22 to move toward the middle of the supporting plate 1, the third elastic member 334 stretches and provides a pulling force, so that the first limit block 332 can be pulled quickly back to the initial position after positioning is completed; when the first limit block 332 is driven to move toward the edge of the supporting plate 1, that is, the side of the first limit frame 333, the third elastic member 334 is compressed and provides elastic force, so that the first limit block 332 will not hit the first limit frame 333 and cause structural damage.

[0059] Reference Figure 4-Figure 6 , Figure 8-Figure 11 ,in Fig. 9 for Figure 8 A partial cross-sectional view of the middle section AA portion shows the structure of the fourth clamping block structure 34; Fig.11 for Fig.10The partial cross-sectional view of the middle section BB portion shows the structure of the fourth clamping block structure 34 after removing the second limit block 342. The fourth clamping block structure 34 also includes a second limit frame 343 and a fourth elastic member 344, wherein the second limit frame 343 is installed at the opening of the second sliding groove 112 close to the edge of the bearing plate 1, and is used to limit the movement of the second limit block 342 to prevent it from falling out of the second sliding groove 112, and the fourth elastic member 344 provides a buffer for the movement of the second limit block 342. A second moving groove 346 is formed between the second limit frame 343 and the bearing plate 1, which is used to further guide and limit the movement of the second limit block 342. The second moving blocks 345 are protruded on both sides of the second limit block 342, and the second moving block 345 slides in the second moving groove 346 to limit its linear movement and prevent the second moving block 345 from falling off in the vertical direction. The fourth elastic member 344 is connected between the second limit frame 343 and the second limit block 342 for buffering. When the second limit block 342 is driven by the second transmission rod 23 to move toward the middle of the supporting plate 1, the fourth elastic member 344 stretches and provides a pulling force, so that the second limit block 342 can be pulled quickly back to the initial position after positioning is completed; when the second limit block 342 is driven to move toward the edge of the supporting plate 1, that is, the side of the second limit frame 343, the fourth elastic member 344 is compressed and provides elastic force, so that the second limit block 342 will not hit the second limit frame 343 and cause structural damage.

[0060] In some embodiments, reference Figure 1-Figure 3 , at least one adsorption member 41 is also provided on the carrier plate 1, which is used to adsorb the carrier on the carrier plate 1 in the vertical direction, i.e., the z-axis direction. According to the actual situation, the adsorption member 41 can be used for pre-adsorption before using the third clamping block structure 33 and the fourth clamping block structure 34, and then further positioning can be performed to prevent the carrier from falling or popping out during positioning due to its thickness and other reasons; or adsorption for z-axis positioning can be performed after the third clamping block structure 33 and the fourth clamping block structure 34 are positioned. Each adsorption member 41 runs through the carrier plate 1 and is connected to the adsorption tube 42. The adsorption tube 42 is used to connect to a vacuum generating structure such as an external vacuum pump to control the adsorption capacity of the adsorption member 41. The adsorption member 41 is located in the area surrounded by the first clamping block structure 31, the second clamping block structure 32, the third clamping block structure 33 and the fourth clamping block structure 34. At least one adsorption member 41 can better adsorb the carrier on the carrier plate 1 and improve the accuracy of positioning.

[0061] In some embodiments, reference Figure 2 , Figure 5-Figure 6The first transmission rod 22 is provided with a third moving groove 26 at one end away from the transmission member 21, and a moving column 71 is installed at the moving end of the driving assembly 7. The moving column 71 is arranged in the third moving groove 26. 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 to buffer the driving of the driving assembly 7 to a certain extent, and guide the movement of the driving assembly 7 through the moving column 71. For the first transmission rod 22, one end thereof 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, driving the first limit block 332 connected thereto 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 toward the inner side of the carrier plate 1, the first transmission rod 22 moves along the x-axis direction, pushing the transmission member 21 to rotate clockwise from the x-axis 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 it slide toward the inner side of the carrier plate 1 in the second transmission groove 14 along the y-axis direction. Through the cooperation of the transmission structure 2, the driving assembly 7 can be installed on the external structure of the carrier plate 1, so that the output in only one direction can realize the movement effect of the first clamping block 331 and the second clamping block 341 in two directions, effectively avoiding the occupation of the space of the carrier plate 1.

[0062] Reference Figure 1-Figure 6 When the carrier needs to be positioned, the first clamping block structure 31 and the second clamping block structure 32 first pre-position the carrier. The driving assembly 7 drives the first transmission rod 22 to drive the first limit block 332 of the third clamping block structure 33 to move in the first sliding groove 111 toward the first clamping block structure 31. At this time, the first moving blocks 335 on both sides of the first limit 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 limit block 342 of the fourth clamping block structure 34 to move in the second sliding groove 112 toward the second clamping block structure 32. At this time, the second moving blocks 345 on both sides of the second limit 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 carrying plate 1 through the first limit block 332 and the second limit block 342 to position the carrier. According to actual conditions, the carrier can be further positioned by the adsorption member 41 to avoid problems such as tilting and sliding when moving the carrier, thereby improving the positioning accuracy.

[0063] Reference Figure 3-Figure 4 , a limiting plate 61 is connected to the outer side of the accommodating slot 12, and the transmission structure 2 is arranged between the accommodating slot 12 and the limiting plate 61. The limiting plate 61 is used to protect the transmission structure 2 from being exposed to the outside and affecting the accuracy of the transmission process. According to actual conditions, a first detection slot 15 is opened in the middle of the carrier plate 1, and a second detection slot 62 is opened at a position corresponding to the first detection slot 15 of the limiting plate 61. A transparent plate 63 is arranged on the first detection slot 15. The positions of the first detection slot 15, the second detection slot 62 and the transparent plate 63 correspond to each other, and are used to expose the marking information of the carrier placed on the carrier plate 1, such as a barcode. A detection component 82 is installed on the outer side of the limiting plate 61. The detection component 82 corresponds to the position of the second detection slot 62, and is used to scan and record the marking information of the carrier. Figure 1-Figure 3 As shown, at least one second sensor 81 is also provided on the carrier 1 to detect whether the carrier is placed on the carrier 1. When it is detected that the carrier is placed on the carrier 1, the detection component 82 can scan the marking information of the carrier through the transparent plate 63 to record and perform the next process flow to improve production efficiency.
