Description

Technical Field

[0001] This invention relates to the technical field of condenser locking devices, and more particularly to a condenser locking and transfer device and a locking and transfer method. Background Technology

[0002] Before entering the dryer, the double-row condensers need to be joined and secured. One employee neatly stacks the two condenser sections, while another employee uses an electric screwdriver to tighten three screws in sequence, securing the two condenser sections together. This manual tightening process involves many steps, a fast production cycle, low efficiency, and is prone to damaging the copper pipes.

[0003] To achieve automatic screw tightening of the double-row condenser, it is necessary to consider the flow of the double-row condensers, their positioning and fixing, and the screw tightening process. To ensure the smooth feeding, tightening, and unloading of the double-row condensers, existing technologies require the use of a single production line for all three processes. This means that when the double-row condensers are being tightened, the entire conveyor line must stop to coordinate with the tightening operation. This method is only suitable for situations where timely and efficient feeding is possible. If there is a break in the double-row condenser section of the conveyor line, it will lead to low transmission efficiency and a slow production cycle. Summary of the Invention

[0004] To overcome the problems existing in related technologies, one of the objectives of this invention is to provide a condenser locking and transfer device with three independently set transmission lines, and the transmission speed and start / stop of each transmission line can be independently controlled. This avoids the problem of low transmission efficiency caused by keeping the entire transmission line synchronized in the prior art, which greatly improves the production cycle and facilitates the loading, unloading and positioning locking operations of the condenser.

[0005] A condenser locking and conveying device includes a feeding conveyor line, a locking conveyor line, and a discharging conveyor line. A positioning and locking component is provided on the side of the locking conveyor line. The output end of the feeding conveyor line is connected to the input end of the locking conveyor line, and the output end of the locking conveyor line is connected to the input end of the discharging conveyor line. The conveying speed of the discharging conveyor line is greater than or equal to the conveying speed of the locking conveyor line, and the conveying speed of the locking conveyor line is greater than the conveying speed of the feeding conveyor line.

[0006] In this application, the conveying speed of the unloading conveyor line is greater than or equal to the conveying speed of the locking conveyor line, ensuring that the condensers entering the unloading conveyor line can be output in a timely manner, and preventing the locked condensers from stacking on the unloading conveyor line; in this application, the conveying speed of the locking conveyor line is greater than the conveying speed of the loading conveyor line, which ensures that the condensers entering the locking conveyor line are spaced apart throughout the entire conveyor line, facilitating the positioning and locking operation of the positioning and locking components. In a preferred embodiment of the present invention, a plurality of waiting positions are sequentially arranged in the feeding conveyor line, and a first photoelectric switch is arranged on the side of the locking conveyor line near the feeding conveyor line; a locking position is arranged in the locking conveyor line, and a second photoelectric switch is arranged in the locking position. When the first photoelectric switch detects that the waiting position is full, and the second photoelectric switch detects that there is a condenser in the locking position, the feeding conveyor line stops running.

[0007] In this application, the first photoelectric switch and the second photoelectric switch are electrically connected to the controller of the feeding conveyor line. Although the first photoelectric switch is located in the locking conveyor line, it faces the feeding conveyor line and is used to monitor whether there is a condenser in the waiting position closest to the locking conveyor line in the feeding conveyor line. The second photoelectric switch is used to monitor whether there is a condenser in the locking position. If there is a condenser in the locking position and there is also a condenser in the waiting position closest to the locking conveyor line in the feeding conveyor line, the controller controls the feeding conveyor line to stop transmitting to avoid the condenser accumulating in the locking position and interfering with the locking operation.

[0008] In a preferred embodiment of the present invention, a vacancy position is provided on the side of the feeding conveyor line near the locking conveyor line, and a third photoelectric switch is provided in the vacancy position; a locking position is provided in the locking conveyor line, and a second photoelectric switch is provided in the locking position. When the third photoelectric switch detects that the vacancy position is full, the locking conveyor line stops operating.

[0009] In this application, the second and third photoelectric switches are electrically connected to the controller of the locking transmission line. Multiple stations for placing condensers can be set in the unloading transmission line. In this application, the placement position closest to the locking transmission line is defined as an empty position. If the third photoelectric switch detects that there is a condenser in the empty position, even if the condenser in the locking position completes the locking operation, the locking transmission line will not output the locked condenser to avoid the condensers from stacking and colliding in the unloading transmission line.

[0010] In a preferred embodiment of the present invention, the conveying surfaces of the feeding conveyor line, the locking conveyor line, and the unloading conveyor line are at the same height; feeding blocking plates are respectively provided on both sides of the feeding conveyor line, locking blocking plates are respectively provided on both sides of the locking conveyor line, and unloading blocking plates are respectively provided on both sides of the unloading conveyor line; the feeding blocking plates, locking blocking plates, and unloading blocking plates are connected by fixing blocks.

[0011] To ensure smooth condenser transport throughout the entire process, this application requires ensuring that the transport surfaces of the three transport lines are at the same height to avoid condenser jamming between adjacent transport lines, which would affect transport efficiency. To limit the condenser's movement perpendicular to the transport direction, this application provides corresponding baffle plates on both sides of each transport line. Multiple baffle plates are fixed together by fixing blocks, forming a unified whole. In this application, the loading baffle plate, locking baffle plate, and unloading baffle plate can be a single elongated plate structure or multiple elongated plate structures. Baffle plates located on the same side are connected by fixing blocks, facilitating the installation and disassembly of the baffle plates.

[0012] In a preferred embodiment of the present invention, the positioning and locking assembly includes a first blocking cylinder and a second blocking cylinder, the first blocking cylinder and the second blocking cylinder being located at opposite ends of the transmission direction in the locking transmission line; a fourth photoelectric switch is disposed below the first blocking cylinder; and a fifth photoelectric switch is disposed below the second blocking cylinder.

[0013] To improve transmission efficiency, this application features only one locking position in the locking transmission line. A first blocking cylinder is located at the front end of the locking position, near the feeding transmission line, and a second blocking cylinder is located at the rear end of the locking position, near the unloading transmission line. When the condenser enters the locking position from the feeding transmission line, the second blocking cylinder drops to prevent the condenser from flowing out of the locking position. When the condenser enters the unloading transmission line from the locking position after locking, the first blocking cylinder drops to prevent the next condenser from entering the locking position before the condenser in the locking position has fully exited. This application also features a fourth photoelectric switch located below the first locking position. When the fourth photoelectric switch detects a condenser, it indicates that the condenser has not fully entered the locking position, and the first blocking cylinder cannot drop. When the fifth photoelectric switch detects a condenser, it indicates that the condenser has not fully flowed out of the locking position, and the second blocking cylinder cannot drop. Through the cooperation of the locking cylinders and the corresponding photoelectric switches, efficient input and output of the condenser in the locking position can be achieved.

[0014] In a preferred embodiment of the present invention, the positioning and locking assembly includes a machine base, in which a hollow area and a locking electric screwdriver are provided, and the locking transmission line is fixed above the hollow area; the locking electric screwdriver is located on the side of the locking transmission line.

[0015] This application secures the locking transmission line to the machine's recessed area using support legs, preventing misalignment between the locking transmission line and the positioning locking components after relocation following commissioning, thus saving commissioning time. The recessed area accommodates components such as the electrical box at the bottom of the locking transmission line, and the lifting and lowering of the support legs allows for adjustment of the locking transmission line's height, ensuring that the locking transmission line, the loading transmission line, and the unloading transmission line are at the same height. When the locking electric screwdriver is aligned with the locking position and the condenser is in the locking position, the through hole to be locked in the locking device is located on the side closest to the locking electric screwdriver.

[0016] In a preferred embodiment of the present invention, the locking electric screwdriver is used to lock and fix the stacked double-row condensers. The double-row condensers include a stacked first condenser and a second condenser. The first condenser has a first through hole on its side, and the second condenser has a protrusion facing the first condenser on its side. The protrusion has a second through hole that matches the first through hole. The locking electric screwdriver is used to lock and fix the first through hole and the second through hole.

[0017] In this application, two rows of condensers are stacked vertically, with the first condenser on top and the second condenser on the bottom. The bottom of the first condenser has a first through hole, and the top of the second condenser has an upward-facing protrusion with a second through hole in the protrusion. When the first and second condensers are stacked, the first and second through holes are aligned. A locking electric screwdriver is then used to lock the first and second through holes, thus securing the two condensers. In this application, the number and position of the first and second through holes and the locking electric screwdriver are all one-to-one.

[0018] In a preferred embodiment of the present invention, the positioning and locking assembly includes a positioning part, which includes a lifting cylinder, a clamping cylinder, and a clamp. The output end of the lifting cylinder is connected to the clamping cylinder, and the output end of the clamping cylinder is connected to the clamp. The clamp includes two opposing jaws, which are located on both sides of the double-row condenser in the transmission direction of the double-row condenser.

[0019] This application defines the side of the double-row condenser closest to the feeding assembly as the front end, the side closest to the unloading assembly as the rear end, the side closest to the locking electric screwdriver as the left end, and the side furthest from the locking electric screwdriver as the right end; two grippers are located at the front and rear ends of the double-row condenser, respectively. During the transfer of the double-row condenser, the lifting cylinder drives the clamping cylinder and the clamps to rise, avoiding interference with the transfer of the double-row condenser; when the double-row condenser is exactly in the locking position, the lifting cylinder descends, ensuring that the grippers are aligned with the front and rear ends of the double-row condenser; the clamping cylinder drives the grippers to clamp the front and rear ends of the double-row condenser and hold them for a period of time, thereby achieving the positioning of the double-row condenser in the front-back direction.

[0020] In a preferred embodiment of the present invention, the positioning part includes a push cylinder and a push plate, the output end of the push cylinder is connected to the push plate, and the push plate is located on the side of the double-row condenser away from the locking electric screwdriver.

[0021] After the dual-row condenser is positioned front and back, the push cylinder pushes it out, causing the dual-row condenser to come into contact with the locking baffle plate located on the side of the locking electric screwdriver, thus positioning the dual-row condenser in the left and right direction.

[0022] In a preferred embodiment of the present invention, the positioning part includes a clamping cylinder and a pressure plate, the output end of the clamping cylinder is connected to the pressure plate, and the pressure plate is located on the side of the double-row condenser away from the locking transmission line.

[0023] After the dual-row condenser is positioned left and right, the clamping cylinder is pushed out, pressing the first and second condensers together to achieve the vertical positioning of the dual-row condenser; ensuring that the first and second through holes are aligned.

[0024] The second objective of this application is to provide a method for locking and transporting a condenser, including: The dual-row condenser is transported from the feeding conveyor line to the locking conveyor line; The lifting cylinder drives the clamping cylinder and the clamp to descend until the clamp is aligned with the double-row condenser; the clamping cylinder drives the clamp to clamp and position both sides of the double-row condenser. The push cylinder drives the push plate to push out, pushing the double-row condenser to a position at a preset distance from the locking electric screwdriver; The clamping cylinder drives the pressure plate to push out, positioning the double-row condenser in the stacking direction; The locking electric screwdriver locks and fixes the first through hole and the second through hole; After being locked, the double-row condenser flows out through the feeding conveyor line.

[0025] The beneficial effects of this invention are as follows: The present invention provides a condenser locking and conveying device, comprising a feeding conveyor line, a locking conveyor line, and a discharging conveyor line. A positioning and locking component is provided on the side of the locking conveyor line. The output end of the feeding conveyor line is connected to the input end of the locking conveyor line, and the output end of the locking conveyor line is connected to the input end of the discharging conveyor line. The conveying speed of the discharging conveyor line is greater than or equal to the conveying speed of the locking conveyor line, and the conveying speed of the locking conveyor line is greater than the conveying speed of the feeding conveyor line. In this application, the conveying speed of the unloading conveyor line is greater than or equal to the conveying speed of the locking conveyor line, ensuring that the condensers entering the unloading conveyor line can be output in a timely manner, and preventing the locked condensers from stacking on the unloading conveyor line. In this application, the conveying speed of the locking conveyor line is greater than the conveying speed of the loading conveyor line, which ensures that the condensers entering the locking conveyor line are spaced apart throughout the entire conveyor line, facilitating the positioning and locking operation of the positioning and locking components. In this application, the three conveyor lines are set independently, and the conveying speed and start / stop of each conveyor line can be controlled independently, avoiding the problem of low conveying efficiency caused by keeping the entire conveyor line synchronized in the prior art, which greatly improves the production cycle and facilitates the loading, unloading, and positioning and locking operations of the condensers.

[0026] This application also provides a condenser locking and transfer method, comprising: the double-row condenser being transferred from the feeding conveyor line to the locking conveyor line; the lifting cylinder driving the clamping cylinder and the clamp to descend until the clamp is aligned with the double-row condenser; the clamping cylinder driving the clamp to clamp and position both sides of the double-row condenser; the pushing cylinder driving the push plate to push the double-row condenser to a position at a preset distance from the locking electric screwdriver; the pressing cylinder driving the pressing plate to push out and position the double-row condenser in the stacking direction; the locking electric screwdriver locking and fixing the first through hole and the second through hole; and the locked double-row condenser flowing out through the unloading conveyor line. In the positioning and locking process, this application first positions the double-row condenser front and back, then positions it left and right, and finally positions it up and down at the same workstation. After positioning, the first and second through holes are locked with a locking electric screwdriver. Combined with the independent three-section transmission line and the setting of the transmission speed, the production cycle is greatly improved, and it is also helpful for the loading, unloading and positioning and locking operations of the condenser.

[0029] Preferred embodiments of the invention will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the invention are shown in the drawings, it should be understood that the invention can be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0030] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The singular forms “a,” “the,” and “the” used in this invention and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used herein refers to and includes any or all possible combinations of one or more of the associated listed items.

[0031] It should be understood that although the terms "first," "second," "third," etc., may be used in this invention to describe various information, this information should not be limited to these terms. These terms are only used to distinguish information of the same type from one another. For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0032] Example 1 like Figures 1-10 As shown, this application provides a condenser locking and conveying device, including a feeding conveyor line 11, a locking conveyor line 12, and a discharging conveyor line 14. A positioning and locking assembly is provided on the side of the locking conveyor line 12. The output end of the feeding conveyor line 11 is connected to the input end of the locking conveyor line 12, and the output end of the locking conveyor line 12 is connected to the input end of the discharging conveyor line 14. The conveying speed of the discharging conveyor line 14 is greater than or equal to the conveying speed of the locking conveyor line 12, and the conveying speed of the locking conveyor line 12 is greater than the conveying speed of the feeding conveyor line 11.

[0033] In this application, the feeding conveyor line 11, the locking conveyor line 12, and the unloading conveyor line 14 are three independent conveyor lines, and their respective conveying speeds and start / stop states can be controlled independently. Among them, the feeding conveyor line 11 has the slowest conveying speed, which is convenient for manual feeding. The locking conveyor line 12 and the unloading conveyor line 14 can have equal conveying speeds, and the locking conveyor line 12 is faster than the conveying speed of the condenser flowing from the feeding conveyor line 11 to the locking conveyor line 12. This ensures that the conveying speed of the condenser flowing from the feeding conveyor line 11 to the locking conveyor line 12 is greater than the conveying speed of the condenser in the feeding conveyor line 11, thereby increasing the distance between the condensers located in the feeding conveyor line 11 and the locking conveyor line 12, which is convenient for positioning and locking in the locking conveyor line 12.

[0034] Similarly, in this application, the transmission rate of the locking transmission line 12 can be less than the transmission rate of the unloading transmission line 14, which helps the unloading transmission line 14 to output the locked condenser in a timely manner.

[0035] In this application, the feeding conveyor line 11 is used for employee feeding. When the locking conveyor line 12 stops operating due to locking, the feeding conveyor line 11 can still operate without interference, so that multiple condensers can be stored in sequence, reducing the time wasted by employees due to handling abnormalities or other reasons.

[0036] In this application, the unloading conveyor line 14 can continuously transport materials. Even when the locking conveyor line 12 stops operating due to locking, the unloading conveyor line 14 can still operate. The condenser that has been locked and flows out of the locking conveyor line 12 is quickly transferred to the next process, ensuring that the unloading conveyor line 14 maintains sufficient empty space 143, thus increasing the flow rate of the condenser.

[0037] In this application, the conveying speed of the unloading conveyor line 14 is greater than or equal to the conveying speed of the locking conveyor line 12, ensuring that the condensers entering the unloading conveyor line 14 can be output in a timely manner, and preventing the locked condensers from stacking in the unloading conveyor line 14. In this application, the conveying speed of the locking conveyor line 12 is greater than the conveying speed of the loading conveyor line 11, which ensures that the condensers entering the locking conveyor line 12 are spaced apart throughout the entire conveyor line, facilitating the positioning and locking operation of the positioning and locking components. In this application, the three conveyor lines are set independently, and the conveying speed and start / stop of each conveyor line can be controlled independently, avoiding the problem of low conveying efficiency caused by keeping the entire conveyor line synchronized in the prior art, which greatly improves the production cycle and facilitates the loading, unloading, and positioning and locking operations of the condensers.

[0038] This application also provides a condenser locking and transfer method, comprising: the double-row condenser 31 being transferred from the feeding conveyor line 11 to the locking conveyor line 12; the lifting cylinder 23 driving the clamping cylinder 24 and the clamp to descend until the clamp is aligned with the double-row condenser 31; the clamping cylinder 24 driving the clamp to clamp and position both sides of the double-row condenser 31; the pushing cylinder 25 driving the push plate to push the double-row condenser 31 to a position at a preset distance from the locking electric screwdriver 132; the pressing cylinder 26 driving the pressing plate to push out and position the double-row condenser 31 in the stacking direction; the locking electric screwdriver 132 locking and fixing the first through hole 313 and the second through hole 315; and the locked double-row condenser 31 flowing out through the unloading conveyor line 14. In the positioning and locking process of this application, the double-row condenser 31 is first positioned front and back at the same workstation, then positioned left and right, and finally positioned up and down. After positioning, the first through hole 313 and the second through hole 315 are locked by locking electric screwdriver 132. With the independent three-section transmission line and the setting of transmission speed, the production cycle is greatly improved, and it is also helpful for the loading, unloading and positioning and locking operations of the condenser.

[0039] Example 2 like Figures 1-10As shown, this application provides a condenser locking and conveying device, including a feeding conveyor line 11, a locking conveyor line 12, and a discharging conveyor line 14. A positioning and locking assembly is provided on the side of the locking conveyor line 12. The output end of the feeding conveyor line 11 is connected to the input end of the locking conveyor line 12, and the output end of the locking conveyor line 12 is connected to the input end of the discharging conveyor line 14. The conveying speed of the discharging conveyor line 14 is greater than or equal to the conveying speed of the locking conveyor line 12, and the conveying speed of the locking conveyor line 12 is greater than the conveying speed of the feeding conveyor line 11.

[0040] Furthermore, the feeding conveyor line 11 is provided with a plurality of waiting positions 111 in sequence, and the locking conveyor line 12 is provided with a first photoelectric switch 121 on the side near the feeding conveyor line 11; the locking conveyor line 12 is provided with a locking position, and a second photoelectric switch 122 is provided in the locking position. When the first photoelectric switch 121 detects that the waiting position 111 is full, and the second photoelectric switch 122 detects that there is a condenser in the locking position, the feeding conveyor line 11 stops running.

[0041] In this application, the first photoelectric switch 121 and the second photoelectric switch 122 are electrically connected to the controller of the feeding conveyor line 11. Although the first photoelectric switch 121 is located in the locking conveyor line 12, it faces the feeding conveyor line 11 and is used to monitor whether there is a condenser in the waiting position 111 closest to the locking conveyor line 12 in the feeding conveyor line 11. The second photoelectric switch 122 is used to monitor whether there is a condenser in the locking position. If there is a condenser in the locking position and there is also a condenser in the waiting position 111 closest to the locking conveyor line 12 in the feeding conveyor line 11, the controller controls the feeding conveyor line 11 to stop conveying, so as to avoid the condenser accumulating in the locking position and interfering with the locking operation.

[0042] Furthermore, the unloading transmission line 14 has an empty position 143 on the side near the locking transmission line 12, and a third photoelectric switch 141 is provided in the empty position 143; the locking transmission line 12 has a locking position, and a second photoelectric switch 122 is provided in the locking position. When the third photoelectric switch 141 detects that the empty position 143 is full, the locking transmission line 12 stops running.

[0043] In this application, the second photoelectric switch 122 and the third photoelectric switch 141 are electrically connected to the controller of the locking transmission line 12. Multiple stations for placing condensers can be set in the unloading transmission line 14. In this application, the placement position closest to the locking transmission line 12 is defined as the empty position 143. If the third photoelectric switch 141 detects that there is a condenser in the empty position 143, even if the condenser in the locking position completes the locking operation, the locking transmission line 12 will not output the locked condenser to avoid the condensers from stacking and colliding in the unloading transmission line 14.

[0044] Furthermore, the heights of the conveying surfaces of the feeding conveyor line 11, the locking conveyor line 12, and the unloading conveyor line 14 are the same; feeding blocking plates 112 are respectively provided on both sides of the feeding conveyor line 11, locking blocking plates 125 are respectively provided on both sides of the locking conveyor line 12, and unloading blocking plates 142 are respectively provided on both sides of the unloading conveyor line 14; the feeding blocking plates 112, locking blocking plates 125, and unloading blocking plates 142 are connected by fixing blocks 32.

[0045] To ensure smooth condenser transport throughout the entire process, this application requires that the transport surfaces of the three transport lines be at the same height to avoid condenser jamming between adjacent transport lines, which would affect transport efficiency. To limit the condenser's movement perpendicular to the transport direction, this application provides corresponding baffle plates on both sides of each transport line. Multiple baffle plates are fixed together by fixing blocks 32, forming a unified whole. In this application, the loading baffle plate 112, locking baffle plate 125, and unloading baffle plate 142 can be a single elongated plate structure or multiple elongated plate structures. Baffle plates located on the same side are connected by fixing blocks 32, facilitating the installation and disassembly of the baffle plates.

[0046] Furthermore, the positioning and locking assembly includes a first blocking cylinder 21 and a second blocking cylinder 22, which are located at opposite ends of the transmission direction in the locking transmission line 12. A fourth photoelectric switch 123 is disposed below the first blocking cylinder 21, and a fifth photoelectric switch 124 is disposed below the second blocking cylinder 22.

[0047] To improve transmission efficiency, this application provides only one locking position in the locking transmission line 12. The first blocking cylinder 21 is located at the front end of the locking position, i.e., near the side of the feeding transmission line 11, and the second blocking cylinder 22 is located at the rear end of the locking position, i.e., near the side of the unloading transmission line 14. When the condenser enters the locking position from the feeding transmission line 11, the second blocking cylinder 22 drops to prevent the condenser from flowing out of the locking position. When the condenser enters the unloading transmission line 14 from the locking position after locking is completed, the first blocking cylinder 21 drops to prevent the next condenser from entering the locking position before the condenser in the locking position has been fully output. This application provides a fourth photoelectric switch 123 on the side below the first locking position. When the fourth photoelectric switch 123 detects the condenser, it indicates that the condenser has not fully entered the locking position, and the first blocking cylinder 21 cannot fall. When the fifth photoelectric switch 124 detects the condenser, it indicates that the condenser has not fully flowed out of the locking position, and the second blocking cylinder 22 cannot fall. Through the cooperation of the locking cylinder and the corresponding photoelectric switch, efficient transmission and transmission of the condenser in the locking position can be achieved.

[0048] Furthermore, the positioning and locking assembly includes a machine base 13, in which a hollow area 131 and a locking electric screwdriver 132 are provided, and the locking transmission line 12 is fixed above the hollow area 131; the locking electric screwdriver 132 is located on the side of the locking transmission line 12.

[0049] This application fixes the locking transmission line 12 in the hollow area 131 of the machine base 13 via the support leg 126, avoiding the problem of relative misalignment between the locking transmission line 12 and the positioning locking assembly due to relocation after debugging, thus saving debugging time. The hollow area 131 is used to accommodate components such as the electrical box at the bottom of the locking transmission line 12, and the lifting and lowering of the support leg 126 can realize the lifting and lowering adjustment of the locking transmission line 12, ensuring that the height of the locking transmission line 12, the feeding transmission line 11, and the unloading transmission line 14 are equal. When the locking electric screwdriver 132 is directly in the locking position, and the condenser is in the locking position, the through hole to be locked in the locking device is located on the side closer to the locking electric screwdriver 132.

[0050] Furthermore, the locking electric screwdriver 132 is used to lock and fix the stacked double-row condensers 31. The double-row condensers 31 include a stacked first condenser 311 and a second condenser 312. The first condenser 311 has a first through hole 313 on its side, and the second condenser 312 has a protrusion 314 facing the first condenser 311 on its side. The protrusion 314 has a second through hole 315 that matches the first through hole 313. The locking electric screwdriver 132 is used to lock and fix the first through hole 313 and the second through hole 315.

[0051] In this application, two rows of condensers 31 are stacked vertically, with the first condenser 311 on top and the second condenser 312 on the bottom. The bottom of the first condenser 311 has a first through-hole 313, and the top of the second condenser 312 has an upward-facing protrusion 314 with a second through-hole 315. When the first condenser 311 and the second condenser 312 are stacked, the first through-hole 313 and the second through-hole 315 are aligned. At this time, the locking electric screwdriver 132 locks the first through-hole 313 and the second through-hole 315, thus locking the two condensers. In this application, the number and position of the first through-hole 313, the second through-hole 315, and the locking electric screwdriver 132 are all one-to-one.

[0052] Furthermore, the positioning and locking assembly includes a positioning part, which includes a lifting cylinder 23, a clamping cylinder 24, and a clamp. The output end of the lifting cylinder 23 is connected to the clamping cylinder 24, and the output end of the clamping cylinder 24 is connected to the clamp. The clamp includes two opposing jaws, which are located on both sides of the double-row condenser 31 in the transmission direction of the double-row condenser 31.

[0053] This application defines the side of the double-row condenser 31 closest to the feeding assembly as the front end, the side closest to the unloading assembly as the rear end, the side closest to the locking electric screwdriver 132 as the left end, and the side furthest from the locking electric screwdriver 132 as the right end; the two grippers are located at the front and rear ends of the double-row condenser 31, respectively. During the transfer of the double-row condenser 31, the lifting cylinder 23 drives the clamping cylinder 24 and the clamp to rise, avoiding interference with the transfer of the double-row condenser 31; when the double-row condenser 31 is exactly in the locking position, the lifting cylinder 23 descends, ensuring that the grippers are aligned with the front and rear ends of the double-row condenser 31; the clamping cylinder 24 drives the grippers to clamp the front and rear ends of the double-row condenser 31 and hold them for a period of time, thereby achieving the positioning of the double-row condenser 31 in the front-rear direction.

[0054] Furthermore, the positioning part includes a push cylinder 25 and a push plate, the output end of the push cylinder 25 is connected to the push plate, and the push plate is located on the side of the double-row condenser 31 away from the locking electric screwdriver 132.

[0055] After the double-row condenser 31 is positioned front and back, the push cylinder 25 is pushed out, so that the double-row condenser 31 abuts against the locking baffle plate 125 located on the side of the locking electric screwdriver 132, thereby positioning the double-row condenser 31 in the left and right directions.

[0056] Furthermore, the positioning part includes a clamping cylinder 26 and a pressure plate, the output end of the clamping cylinder 26 is connected to the pressure plate, and the pressure plate is located on the side of the double-row condenser 31 away from the locking transmission line 12.

[0057] After the dual-row condenser 31 is positioned left and right, the clamping cylinder 26 is pushed out, so that the first condenser 311 and the second condenser 312 are pressed together, thereby positioning the dual-row condenser 31 in the vertical direction; ensuring that the first through hole 313 and the second through hole 315 are aligned.

[0058] Example 3 This application provides a condenser locking and conveying device, including a feeding conveyor line 11, a locking conveyor line 12, and a discharging conveyor line 14. A positioning and locking assembly is provided on the side of the locking conveyor line 12. In this application, all three conveyor lines and the positioning and locking assembly are uniformly controlled by a PLC control center. In this embodiment, the condenser refers to a double-row condenser 31, such as... Figures 8-10As shown, the dual-row condenser 31 includes a first condenser 311 stacked on top and a second condenser 312 stacked on the bottom. The cross-sectional dimension of the first condenser 311 is smaller than that of the second condenser 312, and their locking edges are flush for locking. A first through hole 313 is provided at the bottom of the locking edge of the first condenser 311, and an upward protrusion 314 is provided at the top of the locking edge of the second condenser 312, with a second through hole 315 provided in the protrusion 314. When the first condenser 311 and the second condenser 312 are stacked and aligned, the first through hole 313 and the second through hole 315 are perfectly aligned. A locking electric screwdriver 132 is used to lock and fix the first through hole 313 and the second through hole 315.

[0059] like Figure 2 and Figure 3 As shown, the feeding and conveying station has three waiting positions 111 set in sequence; as Figure 4 As shown, a locking position is provided in the locking transmission line 12; as Figure 6 As shown, three placement positions are arranged sequentially in the feeding conveyor line 14, among which the placement position closest to the locking conveyor line 12 is defined as the vacant position 143.

[0060] A first photoelectric switch 121 is provided on the side of the locking transmission line 12 near the feeding transmission line 11; a locking position is provided in the locking transmission line 12, a second photoelectric switch 122 is provided in the locking position, and a third photoelectric switch 141 is provided in the empty position 143. Although the first photoelectric switch 121 is located in the locking transmission line 12, it faces the feeding transmission line 11 and is used to monitor whether there is a double row of condensers 31 in the waiting position 111 closest to the locking transmission line 12 in the feeding transmission line 11; the second photoelectric switch 122 is used to monitor whether there is a double row of condensers 31 in the locking position; if there is a double row of condensers 31 in the locking position, and there is also a double row of condensers 31 in the waiting position 111 closest to the locking transmission line 12 in the feeding transmission line 11, then the PLC control center controls the feeding transmission line 11 to stop transmission; to avoid the double row of condensers 31 accumulating in the locking position and interfering with the locking operation. If the third photoelectric switch 141 detects that there is a double-row condenser 31 in the empty position 143, even if the double-row condenser 31 in the locking position completes the locking operation, the locking transmission line 12 will not output the locked double-row condenser 31, so as to avoid the double-row condenser 31 from stacking and colliding in the unloading transmission line 14.

[0061] The conveying surfaces of the feeding conveyor line 11, locking conveyor line 12, and unloading conveyor line 14 are at the same height. Feeding blocking plates 112 are provided on both sides of the feeding conveyor line 11, locking blocking plates 125 are provided on both sides of the locking conveyor line 12, and unloading blocking plates 142 are provided on both sides of the unloading conveyor line 14. The feeding blocking plates 112, locking blocking plates 125, and unloading blocking plates 142 are connected by fixing blocks 32. The blocking plates are divided into blocking plates on the locking side and blocking plates on the non-locking side. In this application, the height of the blocking plates on the locking side is less than the height of the first through hole 313 and the second through hole 315 to avoid interference with the locking operation.

[0062] Before locking, the double-row condenser 31 needs to be positioned and aligned. In the prior art, in order to improve the transmission efficiency and production cycle, positioning and locking need to be performed at two workstations. During the transmission between the two workstations, the positioned double-row condenser 31 is prone to positional shift again, causing positioning errors and affecting the final assembly effect. To solve this problem, this application performs in-situ positioning and locking of the double-row condenser 31 at the locking position. The locking device used in this application to realize the positioning and locking functions includes a machine base 13 and a positioning part. The machine base 13 is provided with a hollow area 131 and a locking electric screwdriver 132. The locking transmission line 12 is fixed above the hollow area 131 by a support leg 126; the locking electric screwdriver 132 is located on the side of the locking transmission line 12. The number and position of the first through hole 313, the second through hole 315 and the locking electric screwdriver 132 are all one-to-one.

[0063] The positioning part is set above and to the side of the locking member via the frame 20; wherein, the positioning part includes a first blocking cylinder 21, a second blocking cylinder 22, a lifting cylinder 23, a clamping cylinder 24, a clamp, a pushing cylinder 25, a push plate, a pressing cylinder 26 and a pressure plate; in this application, the side of the double-row condenser 31 near the feeding assembly is the front end, the side near the unloading assembly is the rear end, the side near the locking electric screwdriver 132 is the left end, and the side away from the locking electric screwdriver 132 is the right end; the two grippers are located at the front and rear ends of the double-row condenser 31 respectively. When the double-row condenser 31 enters the locking position from the feeding conveyor line 11, the second blocking cylinder 22 drops to prevent the double-row condenser 31 from flowing out of the locking position. After the double-row condenser 31 is locked, when it enters the unloading conveyor line 14 from the locking position, the first blocking cylinder 21 drops to prevent the next double-row condenser 31 from entering the locking position before the double-row condenser 31 in the locking position has been fully output. This application has a fourth photoelectric switch 123 on the side below the first locking position. When the fourth photoelectric switch 123 detects the double-row condenser 31, it means that the double-row condenser 31 has not fully entered the locking position, and the first blocking cylinder 21 cannot drop. When the fifth photoelectric switch 124 detects the double-row condenser 31, it means that the double-row condenser 31 has not fully flowed out of the locking position, and the second blocking cylinder 22 cannot drop. Through the cooperation of the locking cylinder and the corresponding photoelectric switch, efficient input and output of the double-row condenser 31 in the locking position can be achieved.

[0064] During the transfer of the double-row condenser 31, the lifting cylinder 23 drives the clamping cylinder 24 and the clamp to rise, avoiding interference with the transfer of the double-row condenser 31. When the double-row condenser 31 is in the locking position, the lifting cylinder 23 descends, ensuring that the clamps are aligned with the front and rear ends of the double-row condenser 31. The clamping cylinder 24 drives the clamps to clamp the front and rear ends of the double-row condenser 31 and hold them for a period of time, thus positioning the double-row condenser 31 in the front-back direction. After the double-row condenser 31 is positioned in the front-back direction, the pushing cylinder 25 extends, causing the double-row condenser 31 to abut against the locking baffle plate 125 located on one side of the locking electric screwdriver 132, thus positioning the double-row condenser 31 in the left-right direction. After the double-row condenser 31 is positioned in the left-right direction, the pressing cylinder 26 extends, pressing the first condenser 311 and the second condenser 312 together, thus positioning the double-row condenser 31 in the vertical direction, ensuring that the first through hole 313 and the second through hole 315 are aligned.

[0065] This application also provides a condenser locking and transport method, including: When the first photoelectric switch 121 is triggered, it indicates that the double-row condenser 31 is preparing to enter the locking position from the waiting position 111. At this time, the first blocking cylinder 21 rises and the second blocking cylinder 22 falls. When the fourth photoelectric switch 123 is triggered, it indicates that the double-row condenser 31 is entering the locking position, and the first blocking cylinder 21 cannot fall at this time. When the second photoelectric switch 122 is triggered, it indicates that the double-row condenser 31 has entered the locking position. Until the fourth photoelectric switch 123 is not triggered, it indicates that the double-row condenser 31 has fully entered the locking position, and the first lifting cylinder 23 falls. The locking transmission line 12 stops transmitting.

[0066] The positioning unit first positions the double-row condenser 31 in the locking position: the lifting cylinder 23 descends to ensure that the grippers are aligned with the front and rear ends of the double-row condenser 31; the clamping cylinder 24 drives the grippers to clamp the front and rear ends of the double-row condenser 31 and hold them for a period of time, thereby positioning the double-row condenser 31 in the front-back direction. After the double-row condenser 31 is positioned front-back, the pushing cylinder 25 extends, causing the double-row condenser 31 to abut against the locking stop plate 125 located on one side of the locking electric screwdriver 132, thereby positioning the double-row condenser 31 in the left-right direction. After the double-row condenser 31 is positioned left-right, the pressing cylinder 26 extends, pressing the first condenser 311 and the second condenser 312 together, thereby positioning the double-row condenser 31 in the up-down direction; ensuring that the first through hole 313 and the second through hole 315 are aligned.

[0067] The locking electric screwdriver 132 locks the first through hole 313 and the second through hole 315. After the locking operation is completed, the locking electric screwdriver 132 automatically outputs a success or failure signal to the PLC control center. In this application, the locking electric screwdriver 132 has the function of setting process standards, judging the locking result, and outputting corresponding signals. When the locking result fails, the equipment stops and waits for the employee to handle the abnormality and press the reset button to resume operation.

[0068] After successful locking, if the third photoelectric switch 141 is not triggered, the second blocking cylinder 22 rises and the locking transmission line 12 begins to transmit; if the fifth photoelectric switch 124 is triggered, it indicates that the double-row condenser 31 is flowing out, at which point the second blocking cylinder 22 cannot fall; until the fifth photoelectric switch 124 is not triggered, the second blocking cylinder 22 falls.

[0069] Repeat the above operation to lock all double-row condensers 31; during the above transmission and locking process, if the first photoelectric switch 121 and the second photoelectric switch 122 are triggered simultaneously, the feeding transmission line 11 will stop operating; otherwise, the feeding transmission line 11 will continue to transmit. If the third photoelectric switch 141 and the second photoelectric switch 122 are triggered simultaneously, the locking transmission line 12 will stop operating.

[0070] It should be noted that, in the positioning of the double-row condenser 31, in the first embodiment, the lifting cylinder 23 and clamping cylinder 24 can be reset after being positioned in the front and rear directions, the pushing cylinder 25 can be reset after being positioned in the left and right directions, and the pressing cylinder 26 can be reset after being positioned in the upper and lower directions. In the second embodiment, the lifting cylinder 23, clamping cylinder 24, pushing cylinder 25, and pressing cylinder 26 are held for a period of time after being positioned in the front, rear, left, right, and upper and lower directions, and then reset. In the third embodiment, the lifting cylinder 23, clamping cylinder 24, pushing cylinder 25, and pressing cylinder 26 are positioned in the front, rear, left, right, and upper and lower directions and locked by the locking electric screwdriver 132 before being reset.

[0071] This application may also connect an auxiliary lifting cylinder to the mounting plate of the push cylinder 25. The auxiliary lifting cylinder drives the push cylinder 25 to move up and down, so as to complete the positioning of the left and right sides of the first condenser 311 and the second condenser 312 respectively.

[0072] In the positioning and locking process of this application, the double-row condenser 31 is first positioned front and back at the same workstation, then positioned left and right, and finally positioned up and down. After positioning, the first through hole 313 and the second through hole 315 are locked by locking electric screwdriver 132. With the independent three-section transmission line and the setting of transmission speed, the production cycle is greatly improved, and it is also helpful for the loading, unloading and positioning and locking operations of the condenser.
