Description

Technical Field

[0001] This invention relates to the field of photovoltaic manufacturing equipment technology, and in particular to an automatic loading and unloading system for pressure bars. Background Technology

[0002] As time goes by, the scarcity of fossil fuels becomes increasingly apparent. Against the backdrop of increasingly tight fossil fuel supplies, solar energy, as an inexhaustible renewable energy source, plays a vital role in long-term energy strategies due to its unique cleanliness, safety, and wide availability.

[0003] In the automated manufacturing process of photovoltaics, the basket does not have pressure bars before the silicon wafers undergo pre-cleaning or texturing processes. During the pre-cleaning or texturing process, pressure bars need to be installed on the basket to limit their movement. After the pre-cleaning or texturing process is completed, the pressure bars need to be removed from the basket for the next process. Therefore, the installation and unloading of pressure bars are involved, which in turn requires their transportation.

[0004] In related technologies, pressure bars are generally stacked together and pre-installed in a pressure bar box. The pressure bar box needs to be transported to a predetermined position in advance, and the handling device will take the pressure bars out of the pressure bar box and put them on the basket. This requires ensuring that the pressure bar box remains stationary after reaching the predetermined position. Otherwise, if the pressure bar box is displaced, the handling device will not be able to accurately clamp the pressure bars in the pressure bar box, resulting in the process not being able to proceed normally. Summary of the Invention

[0005] The present invention aims to at least solve one of the technical problems existing in the prior art. To this end, the present invention proposes an automatic loading and unloading system for pressure bars, which can ensure that the pressure bar box is kept stationary after it has been moved into place.

[0006] According to some embodiments of the present invention, an automatic loading and unloading system for pressure bars includes: a pressure bar transfer device for transporting pressure bars to a pressure bar waiting position; a flower basket transfer device for transporting flower baskets to a flower basket waiting position; a loading and unloading device for flower baskets and pressure bars; and a transport device capable of transporting flower baskets located at the flower basket waiting position to the loading and unloading device for flower baskets and pressure bars, and also capable of transporting pressure bars located at the pressure bar waiting position to the loading and unloading device for flower baskets and pressure bars, and also capable of transporting flower baskets on the loading and unloading device for flower baskets and pressure bars to the flower basket waiting position, and also capable of transporting pressure bars on the loading and unloading device for flower baskets and pressure bars to the pressure bar waiting position.

[0007] The pressure bar transfer device includes a first conveying mechanism, a second conveying mechanism, a limiting mechanism, and a lifting mechanism.

[0008] The second conveying mechanism is disposed on the first conveying mechanism, and the conveying direction of the second conveying mechanism is perpendicular to the conveying direction of the first conveying mechanism. The first conveying mechanism can convey the second conveying mechanism to the pressure bar box inlet position, the pressure bar box outlet position, or the pressure bar waiting to be lifted position. The lifting mechanism can lift the pressure bar on the second conveying mechanism located at the pressure bar waiting to be lifted position to the pressure bar waiting to be picked up and placed position. The pressure bar box inlet position, the pressure bar box outlet position, and the pressure bar waiting to be lifted position are arranged sequentially, or the pressure bar box outlet position, the pressure bar box inlet position, and the pressure bar waiting to be lifted position are arranged sequentially. The limiting mechanism is disposed on the conveying path of the first conveying mechanism and is located on the side of the pressure bar waiting to be lifted position away from the pressure bar box outlet position. The limiting mechanism includes a first rotary telescopic member and a snap-fit ​​member drivenly connected to the first rotary telescopic member. The snap-fit ​​member is connected to the side of the first rotary telescopic member close to the pressure bar waiting to be lifted position. The first rotary telescopic member is used to drive the snap-fit ​​member to switch between an avoidance position and a snap-fit ​​position.

[0009] The second conveying mechanism is equipped with two rows of guide rollers, the arrangement direction of which is perpendicular to the conveying direction of the second conveying mechanism. The second conveying mechanism is used to carry the pressure bar box, which is located between the two rows of guide rollers, and the bottom plate of the pressure bar box is provided with a locking interface. When the locking component is in the clearance position, its position is higher than that of the bottom plate of the pressure bar box. When the second conveying mechanism is in the pressure bar lifting position and the locking component is in the locking position, the locking component extends into the locking interface of the bottom plate of the pressure bar box on the second conveying mechanism and pulls the bottom plate of the pressure bar box.

[0010] The automatic loading and unloading system for pressure bars according to embodiments of the present invention has at least the following beneficial effects:

[0011] The pressure bar transfer device is used to transport the pressure bar to the pressure bar waiting position; the flower basket transfer device is used to transport the flower basket to the flower basket waiting position; the handling device can move the flower basket located at the flower basket waiting position to the flower basket and pressure bar loading and unloading device, and can also move the pressure bar located at the pressure bar waiting position to the flower basket and pressure bar loading and unloading device, and can also move the flower basket on the flower basket and pressure bar loading and unloading device to the flower basket waiting position, and can also move the pressure bar on the flower basket and pressure bar loading and unloading device to the pressure bar waiting position.

[0012] Specifically, the automatic loading and unloading system for the pressure bar is set up in two sets, one set is used before the process and the other set is used after the process. Before the process, for this automatic pressure bar loading and unloading system, the flower basket transfer device transports the flower basket to the flower basket waiting position. Then, the handling device moves the flower basket from the waiting position to the flower basket and pressure bar loading and unloading device. The pressure bar transfer device then transports the pressure bar to the pressure bar waiting position. The handling device then moves the pressure bar from the waiting position to the flower basket and pressure bar loading and unloading device. The flower basket and pressure bar loading and unloading device then installs the pressure bar onto the flower basket. The handling device then moves the flower basket with the pressure bar installed to the workbench for processing. After the process is completed, for this automatic pressure bar loading and unloading system after the process, the handling device moves the flower basket with the pressure bar installed back to the flower basket and pressure bar loading and unloading device. The flower basket and pressure bar loading and unloading device then removes the pressure bar from the flower basket. Finally, the handling device moves the flower basket and pressure bar back to the flower basket waiting position and the pressure bar waiting position, respectively.

[0013] For this set of automatic loading and unloading system for pressure bars used before the process, the first conveying mechanism first transports the second conveying mechanism to the pressure bar box feeding position. At this time, the feeding conveying mechanism can transport the pressure bar box carrying the pressure bars to the second conveying mechanism. Then, the first conveying mechanism can transport the pressure bar box loaded with pressure bars to the pressure bar waiting lifting position, waiting for the pressure bars in the pressure bar box to be lifted by the lifting mechanism to the pressure bar waiting to be picked up and placed. When all the pressure bars in the pressure bar box have been taken out by the handling device, the first conveying mechanism can then transport the second conveying mechanism to the pressure bar box discharge position. At this time, the second conveying mechanism can transport the empty pressure bar box to the discharge conveying mechanism.

[0014] For this automatic loading and unloading system for pressure bars used after the process, the first conveying mechanism first transports the second conveying mechanism to the pressure bar box feeding position. At this time, the feeding conveying mechanism can transport the empty pressure bar box to the second conveying mechanism. Then, the first conveying mechanism can transport the empty pressure bar box to the pressure bar waiting lifting position, waiting for the handling device to place the pressure bar in the pressure bar waiting position and be received by the lifting mechanism. As the pressure bars put into the pressure bar box increase, the lifting mechanism gradually descends. When the pressure bars are loaded, the lifting mechanism separates from the bottom pressure bar. The first conveying mechanism can then transport the second conveying mechanism to the pressure bar box discharge position. At this time, the second conveying mechanism can transport the fully loaded pressure bar box to the discharge conveying mechanism.

[0015] Before the second conveying mechanism reaches the lever-lifting position, the first rotary telescopic component drives the locking component in a clearance position. At this time, the locking component is higher than the bottom plate of the lever box. The second conveying mechanism can move normally to the lever-lifting position under the action of the first conveying mechanism, and the locking component will not interfere with the lever box during this process. After the second conveying mechanism is transported to the lever-lifting position, the first rotary telescopic component drives the locking component to the locking position. At this time, the locking component will extend into the locking interface of the bottom plate of the lever box. The first rotary telescopic component can drive the locking component to pull the bottom plate of the lever box. Furthermore, since the lever box is limited by the guide rollers at this time, the lever box can be fixed under the combined action of the guide rollers and the limiting mechanism, which can prevent the lever box from moving arbitrarily and causing the lever to be unable to be accurately picked up and put down.

[0053] Figure 1 A basket 10 is shown for loading silicon wafers 30. (Combined) Figure 1 and Figure 3 Before the pre-cleaning or texturing process of silicon wafer 30, the basket 10 does not have the pressure bar 40. During the pre-cleaning or texturing process of silicon wafer 30, the pressure bar 40 needs to be installed on the basket 10 to limit its position. After the pre-cleaning or texturing process of silicon wafer 30 is completed, the pressure bar 40 needs to be removed from the basket 10. The top of the basket 10 has a slot 11 for assembling the pressure bar 40. The pre-cleaning or texturing process of silicon wafer 30 will be referred to as a process in the following text.

[0054] Figure 2A pressure bar box 20 is shown for loading a pressure bar 40. It includes a base plate 21 and two first side plates 22 disposed on the base plate 21. The two first side plates 22 are arranged side-by-side and spaced apart. Each first side plate 22 has a vertical limiting groove 22a extending through its upper end. The two ends of the pressure bar 40 can be placed in the vertical limiting grooves 22a of the two first side plates 22 respectively. A locking interface 21a is provided on the base plate 21.

[0055] like Figure 4 As shown, the automatic loading and unloading system for pressure rods provided in this application has one function of installing the pressure rod 40 in the pressure rod box 20 onto the flower basket 10, and another function of removing the pressure rod 40 from the flower basket 10.

[0056] Specifically, two sets of automatic loading and unloading systems for the pressure bar are configured, one set used before the process and the other set used after the process. The automatic loading and unloading system for the pressure bar used before the process can install the pressure bar 40 onto the basket 10, and the automatic loading and unloading system for the pressure bar used after the process can remove the pressure bar 40 from the basket 10.

[0057] like Figure 4 As shown, the automatic loading and unloading system for pressure bars includes a pressure bar transfer device 100, a flower basket transfer device 200, a flower basket and pressure bar loading and unloading device 300, and a handling device 400.

[0058] The pressure bar transfer device 100 is used to transport the pressure bar 40 to the pressure bar waiting position; the flower basket transfer device 200 is used to transport the flower basket 10 to the flower basket waiting position; the handling device 400 can handle the flower basket 10 located at the flower basket waiting position to the flower basket and pressure bar loading and unloading device 300, and can also handle the pressure bar 40 located at the pressure bar waiting position to the flower basket and pressure bar loading and unloading device 300, and can also handle the flower basket 10 on the flower basket and pressure bar loading and unloading device 300 to the flower basket waiting position, and can also handle the pressure bar 40 on the flower basket and pressure bar loading and unloading device 300 to the pressure bar waiting position.

[0059] Specifically, the automatic loading and unloading system for pressure bars is configured in two sets, one used before the process and the other used after the process. Before the process, for the set of automatic loading and unloading system used before the process, the flower basket transfer device 200 transports the flower basket 10 to the flower basket waiting position, and then the handling device 400 moves the flower basket 10 from the waiting position to the flower basket and pressure bar loading and unloading device 300. Additionally, the pressure bar transfer device 100 transports the pressure bar 40 to the pressure bar waiting position, and then the handling device 400 moves the pressure bar 40 from the waiting position to the flower basket and pressure bar loading and unloading device 300. Finally, the flower basket and pressure bar loading and unloading device 300 installs the pressure bar 40 onto the flower basket 10. Then, the transport device 400 can transport the flower basket 10 with the pressure bar 40 installed to the workbench 500 for processing; after the process is completed, for this set of automatic loading and unloading system for the pressure bar after the process, the transport device 400 can transport the flower basket 10 with the pressure bar 40 installed to the loading and unloading device 300 for the flower basket and pressure bar, and then the loading and unloading device 300 for the flower basket and pressure bar can remove the pressure bar 40 from the flower basket 10. After that, the transport device 400 can transport the flower basket 10 and the pressure bar 40 to the flower basket waiting position and the pressure bar waiting position respectively.

[0060] It should be noted that the pressure rod transfer device 100 mainly transfers the pressure rod 40 by transferring the pressure rod box 20.

[0061] Combination Figure 5 and Figure 6 In some embodiments, the pressure bar transfer device 100 includes a first conveying mechanism 110, a second conveying mechanism 120, a limiting mechanism 130, and a lifting mechanism 140.

[0062] The first conveying mechanism 110 is used to convey the second conveying mechanism 120.

[0063] Specifically, the first conveying mechanism 110 is a belt conveyor mechanism.

[0064] The second conveying mechanism 120 is disposed on the first conveying mechanism 110. The conveying direction of the second conveying mechanism 120 is perpendicular to the conveying direction of the first conveying mechanism 110. The second conveying mechanism 120 is used to convey the pressure bar box 20.

[0065] Furthermore, the first conveying mechanism 110 can convey the second conveying mechanism 120 to the feed position of the pressure bar box, the discharge position of the pressure bar box, or the pressure bar waiting position; wherein the feed position of the pressure bar box, the discharge position of the pressure bar box, and the pressure bar waiting position are arranged sequentially.

[0066] like Figure 5As shown, it can be understood that when the second conveying mechanism 120 is in the feed position of the pressure bar box, the pressure bar box 20 can be moved to the second conveying mechanism 120 under the conveying of the feed conveying mechanism 150; when the second conveying mechanism 120 is in the discharge position of the pressure bar box, the second conveying mechanism 120 can transport the pressure bar box 20 located on the second conveying mechanism 120 to the discharge conveying mechanism 160; when the second conveying mechanism 120 is in the pressure bar waiting to be lifted position, the pressure bar 40 in the pressure bar box 20 on the second conveying mechanism 120 can be lifted or lowered by the lifting mechanism 140. Both the feed conveying mechanism 150 and the discharge conveying mechanism 160 can be belt conveying mechanisms.

[0067] It should be noted that, for this set of automatic loading and unloading system for pressure bars used before the process, the first conveying mechanism 110 first conveys the second conveying mechanism 120 to the pressure bar box feeding position. At this time, the feeding conveying mechanism 150 can convey the pressure bar box 20 carrying the pressure bars 40 to the second conveying mechanism 120. Then, the first conveying mechanism 110 can convey the pressure bar box 20 carrying the pressure bars 40 to the pressure bar waiting lifting position, waiting for the pressure bars 40 in the pressure bar box 20 to be lifted to the pressure bar waiting to be picked up and placed by the lifting mechanism 140. When all the pressure bars 40 in the pressure bar box 20 are taken out by the handling device 400, the first conveying mechanism 110 can then convey the second conveying mechanism 120 to the pressure bar box discharge position. At this time, the second conveying mechanism 120 can convey the empty pressure bar box 20 to the discharge conveying mechanism 160.

[0068] For this set of automatic loading and unloading system for pressure bars used after the process, the first conveying mechanism 110 first conveys the second conveying mechanism 120 to the pressure bar box feeding position. At this time, the feeding conveying mechanism 150 can convey the empty pressure bar box 20 to the second conveying mechanism 120. Then, the first conveying mechanism 110 can convey the empty pressure bar box 20 to the pressure bar waiting lifting position, waiting for the handling device 400 to place the pressure bar 40 in the pressure bar waiting position and be received by the lifting mechanism 140. As the pressure bar 40 put into the pressure bar box 20 increases, the lifting mechanism 140 gradually descends. When the pressure bar 40 is loaded, the lifting mechanism 140 separates from the lowest pressure bar 40. The first conveying mechanism 110 can then convey the second conveying mechanism 120 to the pressure bar box discharge position. At this time, the second conveying mechanism 120 can convey the fully loaded pressure bar box 20 to the discharge conveying mechanism 160.

[0069] In other embodiments, the pressure bar box discharge position, the pressure bar box feed position, and the pressure bar waiting to be lifted position are arranged sequentially.

[0070] Understandably, the positions of the feed position and the discharge position of the pressure bar box can be interchanged.

[0071] like Figure 8As shown, the second conveying mechanism 120 is further provided with two rows of guide rollers 126. The arrangement direction of the two rows of guide rollers 126 is perpendicular to the conveying direction of the second conveying mechanism 120. The second conveying mechanism 120 is used to carry the pressure bar box 20, which is located between the two rows of guide rollers 126.

[0072] Specifically, each row of guide rollers 126 includes multiple guide rollers 126. The multiple guide rollers 126 in each row are spaced apart along the conveying direction of the second conveying mechanism 120. When the second conveying mechanism 120 is conveying the pressure bar box 20, the guide rollers 126 can guide the pressure bar box 20. In addition, the guide rollers 126 can prevent the pressure bar box 20 from tipping over from the side of the second conveying mechanism 120.

[0073] More specifically, each guide roller 126 is higher than the bearing surface of the second conveying mechanism 120. In other words, when the conveying pressure bar box 20 is placed on the second conveying mechanism 120, the guide roller 126 can contact the pressure bar box 20 and guide the pressure bar box 20.

[0074] like Figure 7 As shown, the limiting mechanism 130 is set on the conveying path of the first conveying mechanism 110 and is located on the side of the pressure bar waiting position away from the pressure bar box discharge position.

[0075] Furthermore, combined Figure 8 , Figure 12 and Figure 13 The limiting mechanism 130 includes a first rotary telescopic member 131 and a locking member 132 drivenly connected to the first rotary telescopic member 131. The locking member 132 is connected to the side of the first rotary telescopic member 131 near the pressure rod to be raised or lowered. The first rotary telescopic member 131 is used to drive the locking member 132 to the avoidance position (e.g., Figure 12 (as shown) and snap-fit ​​position (as shown) Figure 13 Switch between (as shown).

[0076] Specifically, the first rotary telescopic member 131 is a rotary clamping cylinder, whose drive shaft can extend, retract, and rotate. The first rotary telescopic member 131 can drive the locking member 132 to rotate and extend. When the locking member 132 is in the avoidance position, the position of the locking member 132 is higher than the position of the bottom plate 21 of the pressure bar box 20. When the second conveying mechanism 120 is in the pressure bar lifting position and the locking member 132 is in the locking position, the locking member 132 extends into the locking interface 21a of the pressure bar box 20 on the second conveying mechanism 120 and pulls the bottom plate 21 of the pressure bar box 20.

[0077] Understandably, before the second conveying mechanism 120 reaches the lever lifting position, the first rotary telescopic member 131 drives the locking member 132 to be in a clearance position. At this time, the locking member 132 is higher than the bottom plate 21 of the lever box 20. The second conveying mechanism 120 can move normally to the lever lifting position under the action of the first conveying mechanism 110, and the locking member 132 will not interfere with the lever box 20 during this process. After the second conveying mechanism 120 is transported to the lever lifting position, the first rotary telescopic member 131 drives the locking member 132 to be in the locking position. At this time, the locking member 132 will extend into the locking interface 21a of the bottom plate 21 of the lever box 20. At this time, the first rotary telescopic member 131 can drive the locking member 132 to pull the bottom plate 21 of the lever box 20. Furthermore, since the pressure bar box 20 is limited by the guide roller 126 at this time, the pressure bar box 20 can be fixed under the combined action of the guide roller 126 and the limiting mechanism 130, which can prevent the pressure bar box 20 from moving arbitrarily and causing the pressure bar 40 to be unable to be accurately picked up and put down.

[0078] Combination Figure 12 and Figure 13 In some embodiments, the snap-fit ​​member 132 includes a first connecting portion 1321 connected to the first rotary telescopic member 131 and a second connecting portion 1322 connected to the end of the first connecting portion 1321. The second connecting portion 1322 is arranged at an angle to the first connecting portion 1321. The snap-fit ​​member 132 also includes a limiting roller 1323 connected to the second connecting portion 1322.

[0079] Specifically, the first connecting part 1321 and the second connecting part 1322 are arranged vertically. Thus, when the first rotary telescopic member 131 drives the locking member 132 to rotate, the second connecting part 1322 can rotate in the vertical plane, allowing the locking member 132 to switch between a clearance position and a locking position. Furthermore, by providing a limiting roller 1323 on the second connecting part 1322, the limiting roller 1323 can contact the side wall of the locking interface 21a and hold the bottom plate 21 of the pressure bar box 20, reducing the pressure on the bottom plate 21 of the pressure bar box 20 and lowering the risk of wear.

[0080] like Figure 8 As shown, in some embodiments, the second conveying mechanism 120 is provided with a first limiting component 127 and a second limiting component 128 spaced apart along the conveying direction of the second conveying mechanism 120. The first limiting component 127 and the second limiting component 128 are both located on the conveying path of the second conveying mechanism 120, and the pressure bar box 20 is used to limit the first limiting component 127 and the second limiting component 128.

[0081] Specifically, when the pressure bar box 20 is transported to the second conveying mechanism 120, it can be limited by the combined action of the first limiting component 127 and the second limiting component 128.

[0082] Understandably, with the combined limiting of the first limiting component 127, the second limiting component 128, the limiting mechanism 130, and the guide roller 126, the pressure bar box 20 can be limited in four directions (front, back, left, and right), further reducing the risk of instability of the pressure bar box 20.

[0083] Combination Figure 8 and Figure 9 In some embodiments, the first limiting component 127 is located on the side of the second limiting component 128 near the entry end of the second conveying mechanism 120; the first limiting component 127 includes a second rotary telescopic member 1271 and a stop 1272 drivenly connected to the second rotary telescopic member 1271, the second rotary telescopic member 1271 being able to drive the stop 1272 to rotate in a vertical plane to avoid or limit the pressure bar box 20.

[0084] Understandably, when the feeding conveyor 150 conveys the pressure bar box 20 to the second conveying mechanism 120, the stop block 1272 is in a state of avoiding the pressure bar box 20 under the action of the second rotary telescopic member 1271. At this time, the second conveying mechanism 120 can transport the pressure bar box 20 until the pressure bar box 20 abuts against the second limiting component 128. After that, the second rotary telescopic member 1271 can drive the stop block 1272 to rotate and limit the pressure bar box 20.

[0085] The second rotary telescopic member 1271 is a rotary clamping cylinder, whose drive shaft can extend, retract, and rotate. When the drive stop 1272 swings downward, the second rotary telescopic member 1271 can make the stop 1272 avoid the pressure bar box 20. After the drive stop 1272 swings upward, the second rotary telescopic member 1271 pulls the stop 1272, which can make the stop 1272 tighten the pressure bar box 20, thereby limiting the pressure bar box 20.

[0086] like Figure 8 As shown, the second conveying mechanism 120 includes a base frame 121, a drive source 122, a drive wheel, a driven wheel 123, and a belt 124.

[0087] The drive source 122 is fixed on the base frame 121. The drive source 122 is connected to the drive wheel. The driven wheel 123 and the drive wheel are spaced apart along the conveying direction of the second conveying mechanism 120. The two ends of the belt 124 are respectively sleeved on the drive wheel and the driven wheel 123.

[0088] Specifically, the drive source 122 is a motor, and the drive wheel is directly or indirectly connected to the output shaft of the drive source 122. The drive source 122 is used to drive the drive wheel to rotate around the axis of the drive wheel. The drive wheel and the driven wheel 123 are spaced apart, and the axis of the drive wheel and the axis of the driven wheel 123 are parallel and spaced apart. The two ends of the belt 124 are respectively sleeved on the drive wheel and the driven wheel 123. The drive source 122 is used to drive the drive wheel to rotate, thereby making the belt 124 run.

[0089] like Figure 8 As shown, the second conveying mechanism 120 further includes a tension adjustment assembly 125.

[0090] Combination Figure 8 and Figure 10 The driven wheel 123 is connected to a driven shaft 1231 coaxially arranged with the driven wheel 123. The tension adjustment assembly 125 includes a mounting plate 1251 disposed on the base frame 121 and located on the side of the driven wheel 123, an adjustment block 1252 fixed on the mounting plate 1251, and an adjustment rod 1253 threadedly connected to the adjustment block 1252. The adjustment rod 1253 abuts against the side of the driven shaft 1231 near the driving wheel.

[0091] like Figure 11 As shown, specifically, the driven shaft 1231 includes a cylindrical section 12311 and a supporting section 12312. The driven wheel 123 is sleeved on the cylindrical section 12311 and can rotate relative to the cylindrical section 12311. The supporting section 12312 is connected to the cylindrical section 12311 and extends from the side of the driven wheel 123.

[0092] The cross-section of the supporting section 12312 is square.

[0093] like Figure 10 As shown, the mounting plate 1251 is further fixed on the base frame 121 and located on the side of the driven wheel 123. The mounting plate 1251 is used to fix the adjusting block 1252. The adjusting rod 1253 is threadedly connected to the adjusting block 1252. On the one hand, the adjusting rod 1253 can be fixed by the adjusting block 1252. On the other hand, the adjusting rod 1253 abuts against the side of the abutting section 12312 near the driving wheel, which can realize the positioning of the driven wheel 123.

[0094] Furthermore, by rotating the adjusting rod 1253, the position of the adjusting rod 1253 can be changed, thereby adjusting the position of the driven wheel 123, which in turn changes the tension of the belt 124.

[0095] Specifically, the adjusting rod 1253 has a threaded section, and the adjusting block 1252 has a threaded hole that engages with the threaded section. The axial direction of the threaded hole is parallel to the arrangement direction of the driving wheel and the driven wheel 123. Thus, by rotating the adjusting rod 1253, the position of the adjusting rod 1253 can be changed, thereby adjusting the position of the driven wheel 123 and changing the tension of the belt 124.

[0096] Combination Figure 10 and Figure 11 Specifically, in this embodiment, both ends of the cylindrical section 12311 of the driven shaft 1231 are connected to abutment sections 12312. Two tension adjustment components 125 are respectively disposed on both sides of the driven wheel 123, and the adjustment rods 1253 of the two tension adjustment components 125 abut against the abutment sections 12312 at both ends of the cylindrical section 12311. In this way, the stability of the driven wheel 123 during installation can be further improved.

[0097] By placing the pressure box 20 on the second conveying mechanism 120, the pressure box 20 can be transported. By rotating the adjusting rod 1253, the distance between the driving wheel and the driven wheel 123 can be changed, thereby adjusting the tension of the belt 124. In this way, even if there is an error in the installation accuracy of the driving wheel, the position of the driven wheel 123 can be adjusted by the tension adjusting component 125 to ensure that the belt 124 does not become loose.

[0098] Please refer to Figure 10 In some embodiments, the driven shaft 1231 has a positioning hole on the side near the driving wheel, and the adjusting rod 1253 passes through the positioning hole.

[0099] Understandably, the end of the adjusting rod 1253 near the driven shaft 1231 is inserted into the positioning hole, which can ensure the positioning accuracy of the adjusting rod 1253 and the driven shaft 1231. In addition, it can also reduce the risk of misalignment between the adjusting rod 1253 and the driven shaft 1231.

[0100] like Figure 10 As shown, in some embodiments, the mounting plate 1251 is provided with a guide groove 12511 extending along the arrangement direction of the driving wheel and the driven wheel 123, and the driven shaft 1231 passes through the guide groove 12511 and is guided and engaged with the groove wall of the guide groove 12511.

[0101] It is understandable that the guide groove 12511 guides the movement of the driven shaft 1231, ensuring that the driven shaft 1231 and the driven wheel 123 move along the extension direction of the guide groove 12511.

[0102] Specifically, the upper and lower surfaces of the abutting section 12312 are both flat. The abutting section 12312 passes through the guide groove 12511, and the upper and lower surfaces of the abutting section 12312 are in contact with the upper and lower walls of the guide groove 12511. The guide groove 12511 can also prevent the driven shaft 1231 from rotating, thereby preventing the driven shaft 1231 from rotating with the driven wheel 123 when the second conveying mechanism 120 is working.

[0103] like Figure 10 As shown, in some embodiments, the mounting plate 1251 is also provided with a mounting hole located on the side of the driven shaft 1231 away from the driving wheel. The driven shaft 1231 is provided with a screw hole opposite to the mounting hole. The tension adjustment assembly 125 also includes a bolt 1254 that passes through the mounting hole and the screw hole in sequence.

[0104] Understandably, bolt 1254 has a tightening effect on driven shaft 1231, and adjusting rod 1253 has a pushing effect on driven shaft 1231. Both forces can position driven shaft 1231 and ensure the stability of its position. When adjusting the position of driven wheel 123, bolt 1254 and adjusting rod 1253 can be adjusted simultaneously. Furthermore, the combined action of bolt 1254 and adjusting rod 1253 can further improve the installation stability of driven shaft 1231.

[0105] When the pressure box 20 is placed in the second conveying mechanism 120, the pressure box 20 can be transported. By rotating the adjusting rod 1253, the distance between the driving wheel and the driven wheel 123 can be changed, thereby adjusting the tension of the belt 124. In this way, even if there is an error in the installation accuracy of the driving wheel, the position of the driven wheel 123 can be adjusted by the tension adjusting component 125 to ensure that the belt 124 does not become loose, thus improving the reliability and stability of the pressure box 20 transportation process.

[0106] Combination Figure 6 and Figure 14 The lifting mechanism 140 includes a vertical guide frame 141, a lifting drive component 142 disposed on the vertical guide frame 141, and a support plate 143 disposed on the lifting drive component 142. The lifting drive component 142 can drive the support plate 143 to rise and fall, and the support plate 143 can support the pressure rod 40 so that the pressure rod 40 can be lifted or lowered.

[0107] Specifically, the lifting drive component 142 can be a cylinder, a hydraulic cylinder, or an electric lead screw.

[0108] like Figure 15 As shown, the present application provides a flower basket transfer device 200 for transporting a flower basket 10 loaded with silicon wafers 30, which includes a third conveying mechanism 210 and a fourth conveying mechanism 220.

[0109] The third conveying mechanism 210 is used to transport the fourth conveying mechanism 220, which in turn transports the flower basket 10. Under the combined action of the third conveying mechanism 210 and the fourth conveying mechanism 220, the flower basket 10 can be transported in different directions, thereby transporting the flower basket 10 to the flower basket waiting position.

[0110] Specifically, the fourth conveying mechanism 220 is disposed on the third conveying mechanism 210, and the conveying direction of the third conveying mechanism 210 is perpendicular to the conveying direction of the fourth conveying mechanism 220.

[0111] In some embodiments, the third conveying mechanism 210 is a conveyor belt mechanism, and the fourth conveying mechanism 220 is fixed on the belt of the third conveying mechanism 210. Of course, in other embodiments, the third conveying mechanism 210 may also be other types of conveying mechanisms.

[0112] Combination Figure 16 and Figure 17 The fourth conveying mechanism 220 includes a fixed frame 221 disposed on the third conveying mechanism 210 and a conveying component 222 disposed on the fixed frame 221. The conveying component 222 is used for placing the flower basket 10 and can move the flower basket 10 to convey the flower basket 10 to the flower basket waiting position.

[0113] Combination Figure 16 and Figure 17 Furthermore, the third conveying mechanism 210 is provided with a guide rail 211, the length direction of the guide rail 211 is parallel to the conveying direction of the third conveying mechanism 210, and a slider 226 is fixed on the fixed frame 221. The slider 226 is slidably disposed on the guide rail 211. The guide rail 211 can guide the movement of the fixed frame 221 and improve the motion accuracy of the fourth conveying mechanism 220.

[0114] Combination Figure 16 and Figure 17 The fourth conveying mechanism 220 also includes a protective component 223 disposed on the fixed frame 221. The protective component 223 includes two anti-tipping plates 2231. The spacing direction of the two anti-tipping plates 2231 is perpendicular to the conveying direction of the fourth conveying mechanism 220, and a placement space is formed between the two anti-tipping plates 2231 above the conveying component 222.

[0115] Understandably, the flower basket 10 is placed in the space between the two anti-tipping plates 2231 and carried by the conveying assembly 222. Thus, the risk of the flower basket 10 tipping over during transport is reduced by the action of the two anti-tipping plates 2231. Furthermore, since the spacing of the two anti-tipping plates 2231 is perpendicular to the conveying direction of the fourth conveying mechanism 220, the anti-tipping plates 2231 will not interfere with the movement of the flower basket 10 when the conveying assembly 222 moves it.

[0116] In addition, when the third conveying mechanism 210 moves the flower basket 10, the two anti-tipping plates 2231 can also reduce the risk of the flower basket 10 tipping over due to inertia.

[0117] like Figure 17 As shown, in some embodiments, the conveying assembly 222 has a first end 221a and a second end 221b. When the conveying assembly 222 is in a first state, it is used to convey the flower basket 10 from the first end 221a to the second end 221b. When the conveying assembly 222 is in a second state, it is used to convey the flower basket 10 from the second end 221b to the first end 221a.

[0118] It is understood that the conveying assembly 222 has two working states, which are used to convey the flower basket 10 in two different directions. When the conveying assembly 222 is in the first state, it is used to convey the flower basket 10 from the first end 221a to the second end 221b. When the conveying assembly 222 is in the second state, it is used to convey the flower basket 10 from the second end 221b to the first end 221a.

[0119] Combination Figure 17 and Figure 18 The fixing frame 221 is provided with a blocking member 224 located at the first end 221a of the conveying assembly 222. The blocking member 224 is used to limit the flower basket 10 located on the conveying assembly 222.

[0120] Understandably, the blocking member 224 can limit the flower basket 10 on the conveying assembly 222 to prevent the flower basket 10 from falling off the first end 221a of the conveying assembly 222.

[0121] Specifically, there are two blocking members 224. The arrangement direction of the two blocking members 224 is perpendicular to the conveying direction of the fourth conveying mechanism 220. The two blocking members 224 can jointly limit the flower basket 10, further improving the reliability of preventing the flower basket 10 from falling from the first end 221a of the conveying assembly 222.

[0122] Furthermore, a first guide plate 22311 is provided on the side of the anti-tipping plate 2231 near the second end 221b of the conveying assembly 222, and the distance between the first guide plates 22311 on the two anti-tipping plates 2231 gradually decreases along the direction from the second end 221b to the first end 221a of the conveying assembly 222.

[0123] like Figure 15 As shown in Figure 17, it can be understood that for this set of automatic loading and unloading systems for pressure bars used before the process, the baskets 10 on other lines can be transported from the second end 221b of the conveying assembly 222 to the conveying assembly 222. Since the anti-tipping plate 2231 is provided with a first guide plate 22311 on the side near the second end 221b of the conveying assembly 222, and the distance between the first guide plates 22311 on the two anti-tipping plates 2231 gradually decreases along the direction from the second end 221b to the first end 221a, the first guide plates 22311 on the two anti-tipping plates 2231 can pre-guide the baskets 10 so that the baskets 10 enter between the two anti-tipping plates 2231. Specifically, the distance between the first guide plates 22311 on the two anti-tipping plates 2231 gradually decreases along the direction from the second end 221b to the first end 221a of the conveying assembly 222. This can be understood as the distance between the first guide plates 22311 on the two anti-tipping plates 2231 being larger on the side further away from the first end 221a of the conveying assembly 222. This allows for a larger gap between the two anti-tipping plates 2231, facilitating the entry of the flower basket 10.

[0124] Furthermore, a second guide plate 22312 is provided at the top of the anti-tipping plate 2231, and the distance between the second guide plates 22312 on the two anti-tipping plates 2231 gradually increases from bottom to top.

[0125] For this automatic loading and unloading system for pressure bars used after the process, the basket 10 can be placed from top to bottom on the conveying assembly 222 by the conveying device 400. Since the top of the anti-tipping plate 2231 is provided with a second guide plate 22312, the distance between the second guide plates 22312 on the two anti-tipping plates 2231 gradually increases from bottom to top. In this way, the second guide plates 22312 on the two anti-tipping plates 2231 can pre-guide the basket 10 so that it is placed between the two anti-tipping plates 2231 from top to bottom. Once the basket 10 is placed on the conveying assembly 222, it is then conveyed by the conveying assembly 222 to its second end 221b to enter other lines.

[0126] In some embodiments, a camera module is also provided on the fixture 221, which is capable of detecting the silicon wafer 30 inside the basket 10 located on the conveying assembly 222.

[0127] For this automated loading and unloading system for pressure bars used after the process, the basket 10 can be placed on the conveying assembly 222 by the handling device 400. The camera module can detect the silicon wafer 30 inside the basket 10 on the conveying assembly 222. If the detection result is good, the third conveying mechanism 210 moves the fourth conveying mechanism 220 to the first position; if the detection result is bad, the third conveying mechanism 210 moves the fourth conveying mechanism 220 to the second position.

[0128] The quality of the test results can be judged based on the orientation or quantity of the silicon wafers 30 within the basket 10. For example, if the silicon wafers 30 within the basket 10 are misaligned, or if a layer of the basket 10 is missing a silicon wafer 30, it can be considered as poor.

[0129] like Figure 15 As shown, the third conveying mechanism 210 is further provided with two belt lines on its side, one belt line 124 is opposite to the first position and the other belt line 124 is opposite to the second position. Thus, the fourth conveying mechanism 220 can transport the basket 10 to different belt lines 124 according to the quality of the silicon wafer 30 in the basket 10.

[0130] like Figure 17 As shown, in some embodiments, the conveying assembly 222 includes a conveyor belt 2222 and a drive unit 2221 for driving the conveyor belt 2222 to run, with two anti-tipping plates 2231 located on the left and right sides of the conveyor belt 2222 respectively.

[0131] Understandably, the drive unit 2221 is used to drive the conveyor belt 2222 to run, thereby causing the conveyor belt 2222 to drive the flower basket 10 to move; the two anti-tipping plates 2231 are located on the left and right sides of the conveyor belt 2222 respectively. On the one hand, they will not affect the placement of the flower basket 10 on the conveyor belt 2222, and on the other hand, they can prevent the flower basket 10 from tipping over to the left and right sides of the conveyor belt 2222.

[0132] It should be noted that the drive unit 2221 can drive the conveyor belt 2222 to run in the forward or reverse direction, thereby enabling the conveying assembly 222 to switch between the first state and the second state.

[0133] Furthermore, the fourth conveying mechanism 220 also includes two connecting frames 225 respectively connected to both sides of the fixed frame 221, and two anti-tipping plates 2231 are respectively disposed on the two connecting frames 225.

[0134] Specifically, there are two conveyor belts 2222, which are arranged side by side and spaced apart. The two conveyor belts 2222 are located on both sides of the fixed frame 221. The connecting frame 225 passes through the middle area of ​​the conveyor belts 2222 and is connected to the anti-tipping plate 2231.

[0135] More specifically, the drive unit 2221 is a motor, and both ends of the conveyor belt 2222 are sleeved on the drive wheel 2223. Furthermore, one drive wheel 2223 on one conveyor belt 2222 is connected to the drive wheel 2223 on the other conveyor belt 2222 through a drive rod 2224. The drive unit 2221 is used to drive the drive wheel 2223 to rotate, thereby enabling the two conveyor belts 2222 to run simultaneously and in the same direction.

[0136] like Figure 19 , Figure 20 As shown, in some embodiments, the handling device 400 includes a robotic arm 410 and a clamping mechanism 420.

[0137] The robotic arm 410 is the main transporter, which can drive the gripping mechanism 420 to move to different positions.

[0138] Specifically, the robotic arm 410 can drive the gripping mechanism 420 to move up, down, left, and right in space, and the robotic arm 410 can also drive the gripping mechanism 420 to rotate.

[0139] Combination Figure 21 and Figure 22 The clamping mechanism 420 is connected to the robot arm 410. The clamping mechanism 420 includes a mounting frame 421, a flower basket clamping assembly 422, and a pressure bar clamping assembly 423. The mounting frame 421 is connected to the robot arm 410. The flower basket clamping assembly 422 is connected to the bottom of the mounting frame 421, and the pressure bar clamping assembly 423 is connected to the side of the mounting frame 421.

[0140] Specifically, the mounting frame 421 is provided with a connecting seat 4211, and the robot arm 410 is connected to the connecting seat 4211; the flower basket clamping assembly 422 is used to clamp the flower basket 10, and the pressure rod clamping assembly 423 is used to clamp the pressure rod 40; the flower basket clamping assembly 422 is connected to the bottom of the mounting frame 421, and the pressure rod clamping assembly 423 is connected to the side of the mounting frame 421. In this way, when the flower basket clamping assembly 422 is clamping the flower basket 10, the pressure rod clamping assembly 423 will not interfere with the flower basket 10, and when the pressure rod clamping assembly 423 is clamping the pressure rod 40, the flower basket clamping assembly 422 will not interfere with the pressure rod 40.

[0141] For this set of automatic loading and unloading system for pressure bars used before the process, the handling device 400 can first use the robot arm 410 to move the clamping mechanism 420 to the basket waiting position, and then use the basket clamping assembly 422 to clamp the basket 10 fully loaded with silicon wafers 30. Then, the robot arm 410 can transport the basket 10 to the loading and unloading device 300 for baskets and pressure bars. After that, the robot arm 410 can move the clamping mechanism 420 to the pressure bar waiting position, and then use the pressure bar clamping assembly 423 to clamp the pressure bar 40. After that, the robot arm 410 can move the pressure bar 40 to above the basket 10 in the loading and unloading device 300 for baskets and pressure bars so that the pressure bar 40 can be installed on the basket 10.

[0142] For this set of automatic loading and unloading system for pressure bars used after the process, the handling device 400 can first use the robot arm 410 to move the clamping mechanism 420 to the loading and unloading device 300 for flower baskets and pressure bars. Before this, the loading and unloading device 300 for flower baskets and pressure bars has already unloaded the pressure bar 40 from the flower basket 10. The pressure bar clamping component 423 can clamp the pressure bar 40. After that, the robot arm 410 can move the pressure bar 40 to the pressure bar waiting position and put it into the pressure bar box 20. After that, the robot arm 410 can move the clamping mechanism 420 to the loading and unloading device 300 for flower baskets and pressure bars. The flower basket clamping component 422 can clamp the flower basket 10. After that, the robot arm 410 can move the flower basket 10 to the flower basket waiting position.

[0143] The handling device 400 of this application can handle both the flower basket 10 and the pressure bar 40. Compared with the traditional solution that uses two handling devices 400 to handle the flower basket 10 and the pressure bar 40 respectively, it occupies less space and has a lower cost.

[0144] like Figure 21 As shown, in some embodiments, the flower basket clamping assembly 422 includes a drive unit 4221 disposed on the mounting frame 421 and two flower basket clamping members 4222 connected to the lower side of the mounting frame 421. The two flower basket clamping members 4222 are arranged opposite to each other and spaced apart. The drive unit 4221 is used to drive the two flower basket clamping members 4222 to move closer to each other or separate.

[0145] It is understandable that when the drive unit 4221 drives the two flower basket clamping parts 4222 to move closer to each other, it can clamp the flower basket 10; when the drive unit 4221 drives the two flower basket clamping parts 4222 to move apart, it can release the flower basket 10.

[0146] In some embodiments, the drive unit 4221 includes two cylinders, which are used to drive two flower basket clamps 4222 respectively. Under the action of the two cylinders, the two flower basket clamps 4222 can be brought closer to each other or separated.

[0147] In other embodiments, the drive unit 4221 includes a cylinder, which can also bring the two flower basket clamps 4222 closer together or separate when one of the flower basket clamps 4222 moves.

[0148] Of course, the specific structure of the drive unit 4221 is not limited to a cylinder, and can also be other linear drive devices.

[0149] In some embodiments, a positioning post 42221 is provided on the side of any flower basket clamp 4222 near the other flower basket clamp 4222.

[0150] It is understandable that for each flower basket clamp 4222, a positioning post 42221 is provided on the side of it closest to another flower basket clamp 4222.

[0151] like Figure 3 As shown, specifically, the flower basket 10 includes two second side plates, and each of the two second side plates is provided with a limiting hole 12. When the flower basket clamp 4222 clamps the flower basket 10, the positioning post 42221 passes through the limiting hole 12. In this way, the flower basket 10 can be hung up to prevent the flower basket 10 from falling.

[0152] like Figure 21 As shown, further, each of the flower basket clamps 4222 has a plurality of spaced positioning posts 42221 on the side of each flower basket clamp 4222 that is close to the other flower basket clamp 4222.

[0153] Understandably, the second side plate of the flower basket 10 is provided with a plurality of spaced limiting holes 12. The plurality of positioning posts 42221 on the flower basket clamp 4222 can be inserted into the plurality of limiting holes 12 on the second side plate of the flower basket 10. In this way, the hanging capacity of the flower basket 10 can be further improved. In addition, the flower basket 10 can be prevented from rotating, thereby improving safety and reliability.

[0154] like Figure 21 As shown, in some embodiments, the handling device 400 further includes a silicon wafer baffle 4214 connected to the underside of the mounting bracket 421 and located between the two basket clamps 4222.

[0155] Understandably, when the handling device 400 is handling a basket 10 fully loaded with silicon wafers 30 and without the pressure bar 40 installed, the silicon wafer baffle 4214 can limit the silicon wafers 30 and prevent them from falling during handling.

[0156] The mounting bracket 421 is connected to a first connecting plate 4212, and the silicon wafer baffle 4214 is connected to a second connecting plate 4213. The second connecting plate 4213 is height-adjustably connected to the first connecting plate 4212. In this way, the height of the silicon wafer baffle 4214 can be adjusted according to the height of the silicon wafer 30 to ensure the limiting effect of the silicon wafer baffle 4214.

[0157] Specifically, the first connecting plate 4212 is provided with a plurality of assembly holes spaced apart vertically, and the second connecting plate 4213 is provided with an assembly groove 42131 extending vertically. The assembly groove 42131 corresponds to the assembly holes. The conveying device 400 also includes fasteners that pass through the assembly groove 42131, and the fasteners can optionally pass through any of the assembly holes.

[0158] It is understandable that after the height of the second connecting plate 4213 is adjusted, fasteners can be used to fix the second connecting plate 4213 by passing through the assembly slot 42131 and the corresponding assembly hole.

[0159] Specifically, the fastener is a screw, and the mounting hole is a screw hole.

[0160] Combination Figure 21 and Figure 22 In some embodiments, the pressure bar clamping assembly 423 includes a slide cylinder 4231 disposed on the mounting bracket 421 and two pressure bar clamping members 4232 disposed on the slide cylinder 4231. The two pressure bar clamping members 4232 are arranged in pairs, and the slide cylinder 4231 is used to drive the two pressure bar clamping members 4232 to move closer to each other or separate.

[0161] It is understandable that the slide cylinder 4231 guides the pressure rod clamping member 4232, and also drives the pressure rod clamping member 4232. When the slide cylinder 4231 drives the two pressure rod clamping members 4232 to move closer to each other, the pressure rod 40 can be clamped. When the slide cylinder 4231 drives the two pressure rod clamping members 4232 to move apart, the pressure rod 40 can be released.

[0162] In this embodiment, a limiting groove 42321 is provided on the side of any pressure bar clamping member 4232 that is close to the other pressure bar clamping member 4232.

[0163] Specifically, for each pressure bar clamp 4232, a limiting groove 42321 is provided on the side of the clamp 4232 closest to the other pressure bar clamp 4232. The pressure bar 40 can be confined within the limiting grooves 42321 of the two pressure bars 40 to prevent it from falling off.

[0164] Among them, the limiting groove 42321 is a V-shaped groove.

[0165] like Figure 23As shown, in some embodiments, the loading and unloading device 300 for the flower basket and the pressure bar includes a positioning platform 310, a lifting mechanism 320 disposed on the positioning platform 310, and a clamp 330 disposed on the lifting mechanism 320 capable of clamping the pressure bar 40.

[0166] The positioning platform 310 is used for placing the flower basket 10. When the conveying device 400 transports the pressure rod 40 to the loading and unloading device 300 located above the flower basket and the pressure rod, the clamp 330 holds the pressure rod 40, and then the lifting mechanism 320 drives the pressure rod 40 to descend so that the pressure rod 40 is pressed into the slot 11 of the flower basket 10.

[0167] Furthermore, the clamp 330 can also drive the pressure rod 40 to rotate, so that the pressure rod 40 rotates 90° clockwise in the slot 11 of the basket 10, so as to engage the pressure rod 40 in the slot 11.

[0168] The clamp 330 includes a clamping member 331, a horizontal drive member 332 for driving the clamping member 331 to move horizontally, and a rotary drive member 333 for driving the clamping member 331 to rotate. The horizontal drive member 332 is a cylinder, the rotary drive member 333 is a motor, and the lifting mechanism 320 is a cylinder.

[0169] When it is necessary to remove the pressure rod 40 from the basket 10, the clamp 330 first clamps the pressure rod 40, then drives the pressure rod 40 to rotate 90° counterclockwise, then the lifting mechanism 320 pushes the pressure rod 40 out, and then the conveying device 400 clamps the pressure rod 40 away.

[0170] It should be noted that the loading and unloading device 300 for the flower basket and pressure bar is prior art, and for details, please refer to the patent document with announcement number CN217768331U.

[0171] like Figure 4As shown, the automatic loading and unloading system for pressure bars in this application is configured in two sets, one set used before the process and the other set used after the process. Before the process, for the set used before the process, the flower basket AGV trolley transports the flower basket 10 without the pressure bar 40 to the flower basket transfer device 200. The flower basket transfer device 200 transports the flower basket 10 to the flower basket waiting position. Then, the handling device 400 transports the flower basket 10 located at the flower basket waiting position to the loading and unloading device 300 for flower baskets and pressure bars. Additionally, the pressure bar box AGV trolley transports the pressure bar box 20 containing the pressure bar 40 to the pressure bar transfer device 100. The pressure bar transfer device 100 transports the pressure bar 40 to the pressure bar waiting position. The transport device 400 then transports the pressure bar 40 located at the pressure bar waiting position to the flower basket and pressure bar loading and unloading device 300. After that, the flower basket and pressure bar loading and unloading device 300 installs the pressure bar 40 onto the flower basket 10. When all the pressure bars 40 in the pressure bar box 20 are taken out, the pressure bar transfer device 100 moves the empty pressure bar box 20 out and the pressure bar box AGV trolley transfers it to the set of automatic pressure bar loading and unloading systems used after the process. Then, the transport device 400 can transport the flower basket 10 with the pressure bar 40 installed to the workbench 500 for processing. After the process is completed, for this set of automatic loading and unloading system for pressure bars used after the process, the handling device 400 can transport the flower basket 10 with pressure bars 40 installed on the workbench 500 to the loading and unloading device 300 for flower baskets and pressure bars. Then, the loading and unloading device 300 for flower baskets and pressure bars can remove the pressure bars 40 from the flower basket 10. The empty pressure bar box 20 transported by the pressure bar box AGV trolley flows into the pressure bar transfer device 100. The pressure bar transfer device 100 transports the pressure bar box 20 to the lifting mechanism 140. The handling device 400 can transfer the removed pressure bars 40 to the top of the empty pressure bar box 20. With the help of the lifting mechanism 140, the pressure bars 40 are placed into the pressure bar box 20 in sequence. In addition, the handling device 400 can also transfer the pressure bar box 20 with the pressure bars 40 unloaded to the flower basket waiting position of the flower basket transfer device 200 so that the flower basket transfer device 200 can transport the flower basket 10 out.
