Description

Technical Field

[0001] The utility model relates to the field of silicon rod splicing devices, in particular to a splicing seam positioning device and a splicing production line. Background Art

[0002] At present, in the photovoltaic field, in the process of processing silicon rods, silicon rod waste of different sizes and lengths will be generated. In order to avoid waste, the silicon rod waste needs to be recycled. In the prior art, multiple shorter silicon rods are often spliced ​​to form a silicon rod of usable length. During the splicing process, the silicon rods often need to be positioned to control the seams between the silicon rods.

[0003] However, in the existing crystal rod splicing line, when splicing three silicon rods, it is often necessary to position two silicon rods by a splicing seam positioning device, and after the two silicon rods are glued by a gluing device, the spliced ​​silicon rods and the third silicon rod are re-positioned by the splicing seam positioning device, and the gluing device performs secondary gluing, so as to obtain silicon rods that meet the use requirements. In the process of splicing three silicon rods, since the existing silicon rod splicing seam positioning device can only position two silicon rods at the same time, it is necessary to position and glue the three silicon rods twice, which leads to low silicon rod splicing efficiency.

[0050] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0051] Please refer to Figures 1 to 8One embodiment of the utility model provides a seam positioning device, which includes a support seat 100, a first splicing component 21, a second splicing component 22 and a third splicing component 23. The support seat 100 is provided with a to-be-spliced ​​area 10, in which at least two to-be-spliced ​​pieces arranged in sequence along a preset direction are placed. The first splicing component 21 and the second splicing component 22 are arranged on the support seat 100 at intervals along a preset direction, and the first splicing component 21 is movably arranged in a direction close to or away from the second splicing component 22. The first splicing component 21 is used to position and connect the first to-be-spliced ​​piece, and the second splicing component 22 is used to position and connect the second to-be-spliced ​​piece. The third splicing component 23 is movably arranged on the support seat 100 along a preset direction, and the third splicing component 23 has a positioning connection state and a first avoidance state. When the third splicing component 23 is in a positioning connection state, the third splicing component 23 is used to position and connect the third piece to be spliced ​​between the first piece to be spliced ​​and the second piece to be spliced, and the third splicing component 23 can be movably arranged between the first splicing component 21 and the second splicing component 22 along a preset direction; when the third splicing component 23 is in a first avoidance state, the third splicing component 23 avoids the area to be spliced ​​10.

[0052] With the seam positioning device provided by this embodiment, when three pieces to be spliced ​​need to be spliced, the third positioning component switches to the positioning connection state, the third positioning component drives the third piece to be spliced ​​to move between the first positioning component and the second positioning component, and the first positioning component drives the first piece to be spliced ​​to move, so that the spacing between the third piece to be spliced ​​and the second piece to be spliced, and the spacing between the first piece to be spliced ​​and the third piece to be spliced ​​respectively reach the required distance, thereby achieving the positioning of the three pieces to be spliced. When two pieces to be spliced ​​need to be spliced, the third positioning component switches to the first avoidance state, the third positioning component avoids the splicing area 10, and the first positioning component drives the first piece to be spliced ​​to approach or move away from the second piece to be spliced, so that the distance between the first piece to be spliced ​​and the second piece to be spliced ​​reaches the required distance. The seam positioning device can position both two pieces to be spliced ​​and three pieces to be spliced ​​by switching the positioning connection state and the first avoidance state of the third positioning component, thereby improving the working efficiency of the seam positioning device when multiple pieces to be spliced ​​need to be spliced.

[0053] Specifically, the second splicing assembly 22 can be movably disposed on the support base 100 , or can be fixedly disposed on the support base 100 .

[0054] Specifically, the preset direction is as follows: Figure 1 As shown in AB in FIG. 1 , the preset direction corresponds to being parallel to the long side direction of the support base 100 .

[0055] In this embodiment, the third splicing assembly 23 includes a support member 231 and a clamping portion 232. The support member 231 is movably disposed on the support seat 100, and the clamping portion 232 is movably disposed on the support member 231. The clamping portion 232 has a clamping state for clamping the third piece to be spliced ​​and a loosening state for avoiding the area to be spliced ​​10. When the third splicing assembly 23 is in the positioning connection state, the clamping portion 232 is in the clamping state; when the third splicing assembly 23 is in the first avoiding state, the clamping portion 232 is in the loosening state. In this way, the clamping part 232 is driven to move on the support seat 100 by the movably arranged supporting member 231. When the third splicing component 23 is in the positioning connection state, the clamping part 232 is in the clamping state, and the third piece to be spliced ​​is clamped by the clamping part 232 to move between the first piece to be spliced ​​and the second piece to be spliced, and the first splicing component 21 can drive the first piece to be spliced ​​to move, so that the distance between the third piece to be spliced ​​and the first piece to be spliced ​​and the second piece to be spliced ​​can be adjusted so that they can all reach the required spacing, thereby realizing the positioning of the three pieces to be spliced; when the third splicing component 23 is in the first avoidance state, the clamping part 232 is in the loosened state, and the clamping part 232 in the loosened state can avoid the first piece to be spliced, the second piece to be spliced, the first splicing component 21, and the second splicing component 22, so as to avoid the third splicing component 23 interfering with the positioning of the first piece to be spliced ​​and the second piece to be spliced.

[0056] Specifically, the clamping portion 232 is clamped in the middle of the third piece to be assembled, and the distances between the two ends of the third piece to be assembled and the first piece to be assembled and the second piece to be assembled are adjusted through the movement of the support member 231 and the first assembly 21 .

[0057] In this embodiment, the seam positioning device further includes a first guide portion 31 and a second guide portion 32 for guiding cooperation. The first guide portion 31 is arranged on the support seat 100, and the first guide portion 31 is arranged on the side of the area to be spliced ​​10; the second guide portion 32 is arranged at the bottom of the support member 231, and the first guide portion 31 and the second guide portion 32 are guided and cooperated; wherein, at least one of the first guide portion 31 and the second guide portion 32 extends along a preset direction. In this way, the first guide portion 31 is at the side of the area to be spliced ​​10, and the second guide portion 32 is arranged at the bottom of the support member 231. The movement of the support member 231 is realized by the cooperation of the first guide portion 31 and the second guide portion 32, and the support member 231 can drive the clamping portion 232 to move, thereby realizing the adjustment of the distance between the third piece to be spliced ​​and the second piece to be spliced.

[0058] In this embodiment, the clamping part 232 includes a first clamping member 2321 and a second clamping member 2322 which are arranged at intervals, and at least one of the first clamping member 2321 and the second clamping member 2322 moves in a direction close to or away from the other of the first clamping member 2321 and the second clamping member 2322. In this way, when the third splicing component 23 is in a positioning connection state, the first clamping member 2321 and the second clamping member 2322 are close to each other, so that the third to-be-assembled piece can be clamped, and the clamping part 232 is in a clamping state at this time; when the third splicing component 23 is in a first avoidance state, the first clamping member 2321 and the second clamping member 2322 are away from each other, so that the clamping part 232 is switched to a loose state. Therefore, the switching of the state of the clamping part 232 is achieved by the approach or distance of the first clamping member 2321 and the second clamping member 2322.

[0059] Specifically, the clamping portion 232 also includes a parallel cylinder 2323, through which the movement of the first clamping member 2321 and the second clamping member 2322 is realized, and under the action of the parallel cylinder 2323, the movement of the first clamping member 2321 and the second clamping member 2322 is synchronized, thereby ensuring that the clamping position of the first clamping member 2321 and the second clamping member 2322 is always in the middle of the clamping portion 232, thereby ensuring that the end of the third piece to be assembled can be aligned with the end of the first piece to be assembled and the second piece to be assembled.

[0060] In this embodiment, the first splicing component 21 includes a splicing piece 211 and an adsorbing piece 212. The splicing piece 211 is movably arranged on the support seat 100 along a preset direction. The adsorbing piece 212 is arranged on the splicing piece 211. The adsorbing end of the adsorbing piece 212 is located on a side of the splicing piece 211 close to the second splicing component 22 or flush with the splicing piece 211. The adsorbing piece 212 is used to adsorb the first piece to be spliced ​​on the splicing piece 211. In this way, one end of the first piece to be spliced ​​is adsorbed on the splicing piece 211 by the adsorbing piece 212, thereby realizing the positioning connection of the first piece to be spliced, and the movement of the second piece to be spliced ​​is driven by the movement of the splicing piece 211 to adjust the distance between the other end of the first piece to be spliced ​​and the second piece to be spliced ​​or the third piece to be spliced.

[0061] In this embodiment, the seam positioning device also includes a first support bar 11 and a second support bar 12 that are spaced apart, and the first support bar 11 and the second support bar 12 both extend in a preset direction, and the first support bar 11 and the second support bar 12 enclose an area to be spliced ​​10. Among them, the splicing piece 211 is movably arranged between the first support bar 11 and the second support bar 12 along the preset direction, and at least part of the splicing piece 211 extends out of the first support bar 11 and the second support bar 12. In this way, the area to be spliced ​​10 is enclosed by the first support bar 11 and the second support bar 12, thereby realizing the placement of the splicing piece to be spliced, so that each positioning assembly can position and connect the splicing piece to be spliced. In addition, the splicing piece 211 of the first splicing assembly 21 is between the first support bar 11 and the second support bar 12, so as to avoid the first support bar 11 and the second support bar 12 from interfering with the movement of the first splicing assembly 21.

[0062] Specifically, the first support bar 11 and the second support bar 12 are both made of non-metallic polymer materials, and will not damage the pieces to be spliced ​​during the movement of the pieces to be spliced, thereby improving the quality of the product.

[0063] In this embodiment, the seam positioning device further includes a centering positioning assembly 40, which includes a first positioning member 41 and a second positioning member 42 arranged at intervals, the first positioning member 41 can be movably arranged on the side of the first support bar 11 away from the second support bar 12, the second positioning member 42 can be movably arranged on the side of the second support bar 12 away from the first support bar 11, and the first positioning member 41 and the second positioning member 42 both extend along a preset direction. The centering positioning assembly 40 has a positioning state and a second avoidance state; wherein, when the centering positioning assembly 40 is in the positioning state, the first positioning member 41 and the second positioning member 42 are close to each other to position at least two pieces to be spliced; when the centering positioning assembly 40 is in the second avoidance state, the first positioning member 41 and the second positioning member 42 avoid the setting of the area to be spliced ​​10. In this way, after the pieces to be assembled are placed in the area 10 to be assembled, the centering positioning component 40 is switched to the positioning state, and the first positioning component 41 and the second positioning component 42 are close to each other. Since the first positioning component 41 and the second positioning component 42 both extend along a preset direction, the first positioning component 41 and the second positioning component 42 clamp the pieces to be assembled, thereby being able to adjust the direction of the pieces to be assembled, so that each positioning component can position and connect each piece to be assembled.

[0064] Specifically, the movement of the first positioning member 41 and the second positioning member 42 is synchronous, which can ensure that the first positioning member 41 and the second positioning member 42 can always position each piece to be assembled in the middle of the piece to be assembled area 10, so that each positioning component can position and connect each piece to be assembled.

[0065] Specifically, the centering and positioning assembly 40 further includes a centering driving mechanism 43 , and the centering driving mechanism 43 drives the first positioning member 41 and the second positioning member 42 to move.

[0066] In this embodiment, the first splicing assembly 21 also includes a driving structure 213, and the driving part of the driving structure 213 is movably arranged between the first support bar 11 and the second support bar 12 along a preset direction, and the driving part of the driving structure 213 is drivingly connected to the splicing piece 211. In this way, the splicing piece 211 is driven by the driving part to move, thereby driving the movement of the first splicing piece, thereby achieving the adjustment of the position of the first splicing piece. In addition, the driving part is movably arranged between the first support bar 11 and the second support bar 12 along a preset direction, which can prevent the first support bar 11 and the second support bar 12 from interfering with the movement of the driving part.

[0067] Specifically, the driving structure 213 may be a drag chain structure.

[0068] In this embodiment, the second splicing component 22 includes a clamping member 221 and a position detection member 222. The clamping member 221 is arranged at the ends of the first support bar 11 and the second support bar 12, and the clamping member 221 is used to clamp the first piece to be spliced; the position detection member 222 is arranged on the clamping member 221, and the position detection member 222 is located in the clamping gap of the clamping member 221, and the detection head of the position detection member 222 is arranged toward the area to be spliced ​​10. In this way, the end of the second piece to be spliced ​​can be clamped by the clamping member 221, so as to adjust the distance between the first piece to be spliced ​​and the second piece to be spliced ​​by the first positioning member, or adjust the distance between the third piece to be spliced ​​and the second piece to be spliced ​​by the third positioning member. In addition, by arranging the position detection member 222 on the clamping member 221, the position of the end of the second piece to be spliced ​​on the clamping member 221 can be detected by the position detection member 222, so as to facilitate the subsequent process.

[0069] In this embodiment, the seam positioning device also includes a visual detection component 51 and a driving member 52. The visual detection component 51 is arranged on the support seat 100. The visual detection component 51 is spaced apart from the area to be spliced ​​10, and the detection head of the visual detection component 51 is arranged toward the area to be spliced ​​10; the driving member 52 is movably arranged on the support seat 100 along a preset direction, and the driving end of the driving member 52 is drivingly connected to the visual detection component 51. In this way, the spacing between each piece to be spliced ​​can be detected by the visual detection component 51, so as to adjust the position of the first piece to be spliced ​​or the third piece to be spliced. In addition, the visual detection component 51 is driven to move by the driving member 52. After the first piece to be spliced ​​or the third piece to be spliced ​​moves, the position of the visual detection component 51 can be adjusted, so as to ensure the accuracy of the visual detection component 51 in detecting the spacing between each piece to be spliced.

[0070] Another embodiment of the utility model provides a splicing line, including the splicing seam positioning device in the above embodiment, and the splicing line is used to splice crystal rods. The crystal rods are positioned by the splicing seam positioning device, so that the subsequent process flow of the crystal rods can be facilitated, for example, the positioned crystal rods can be glued to achieve the splicing of the crystal rods. Specifically, the crystal rods can be silicon rods.

[0073] Step 2: The equipment detects the material and starts to assemble the rods. The centering and positioning mechanism (equivalent to the centering and positioning component 40) works to center the silicon rods. The servo module (equivalent to the centering drive mechanism 43) determines the silicon rod specifications according to the torque feedback and position feedback.

[0074] Step 3: The cylinder of the end clamping mechanism (equivalent to the second splicing assembly 22) is actuated to clamp the first silicon rod (the second piece to be spliced), and the placement position is moved;

[0076] Step 5: The end positioning device (equivalent to the first splicing component 21), the servo module (equivalent to the driving structure 213) + the vacuum suction cup mechanism (equivalent to the adsorption component 212) drive the end silicon rod (equivalent to the first splicing component) to move, and accurately control the size of the gap L to meet the process index requirements;

[0077] Step 6: The visual mechanism re-measures the width L of the gap to determine whether it is consistent with the process indicators;

[0078] Step 7: The laser distance measuring mechanism (position detection element 222) is tested to accurately measure the end surface to ensure the gluing accuracy of the next gluing process;

[0079] Step 8: Notify the system to start taking out the spliced ​​silicon rods.

[0080] Specifically, Figure 8As shown, when three silicon rods are spliced ​​using the crystal rod splicing assembly line provided in this embodiment, the following process can be adopted:

[0081] Step 1: The feeding fixture uses a truss, a robotic arm or other actuators to place the silicon rods on the rod positioning device and sends a discharge completion signal to the device;

[0082] Step 2: The equipment detects the material and puts the rods together. The centering and positioning mechanism works to center the silicon rods. The servo module determines the specifications of the silicon rods based on the torque feedback and position feedback.

[0083] Step 3: The cylinder of the end clamping mechanism moves to clamp the first silicon rod, and the placement position moves;

[0084] Step 4: The servo module drives the visual mechanism to take pictures, accurately measure the length of each silicon rod, the gap L and the size of the silicon rod, and guide the positioning mechanism to assemble the rods;

[0085] Step 5: The servo module (equivalent to the second guide part 32) + parallel cylinder mechanism (equivalent to the clamping part 232) of the intermediate positioning device (equivalent to the third splicing component 23) drives the intermediate silicon rod (equivalent to the third piece to be spliced) to move, and accurately controls the size of the gap L to meet the process index requirements;

[0086] Step 6: The visual mechanism re-measures the width L of the gap to determine whether it is consistent with the process indicators;

[0087] Step 7: The servo module + vacuum suction cup mechanism of the end positioning device drives the end silicon rod to move, and accurately controls the size of the gap L to meet the process index requirements;

[0088] Step 8: The visual mechanism re-measures the width L of the gap to determine whether it is consistent with the process indicators;
