Description

A conveying device for automotive capacitor production Technical Field

[0001] This invention relates to the field of material conveying devices, and more particularly to a handling device for automotive capacitor production. Background Technology

[0002] Automotive antenna capacitors are automotive components that enhance the signal reception capability of antennas, reduce interference and noise, and thus improve radio reception. Capacitor testing and packaging are steps in the capacitor production process. Currently, capacitors are processed using a single-capacitor assembly line method. The process includes bare product loading, polarity detection, first lead cutting, lead flattening, mounting, second lead cutting, printing, testing, and packaging. Capacitors to be processed are typically arranged neatly in trays. A robotic arm then picks up the capacitors from the trays and places them into the corresponding equipment for processing. Current tray loading devices are generally back-and-forth moving conveyors with tray racks. During loading, workers place the trays onto the racks, and the conveyor moves the tray racks backward to a designated position. Then, the robotic arm loads the capacitors. After all capacitors on the trays are picked up, the tray rack is pushed out, and workers remove the empty trays and replace them with new, fully loaded ones. Some of the material trays are quite heavy. After retrieving the trays containing capacitors from the warehouse, workers use trolleys to transport them to the loading area. Then, they manually load and unload the trays one by one. Empty trays still need to be unloaded and stacked after being discharged before being moved away. This results in high labor intensity, high labor costs, and low production efficiency. To address this issue, a handling device for automotive capacitor production was designed. Summary of the Invention

[0003] The present invention provides a handling device for automotive capacitor production, which solves the above-mentioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A handling device for automotive capacitor production includes a loading rack, a unloading rack on the left side of the loading rack, a trolley placed inside both the loading rack and the unloading rack, a material tray placed on the trolley, positioning grooves on both the front and rear sides of the upper surface of the material tray, support columns at the four corners below the material tray, and slots for engaging the support columns at the four corners above the material tray. A picking rack is provided between the loading rack and the unloading rack, and a lifting structure is installed at the rear of both the loading rack and the unloading rack. The lifting structure is equipped with lifting components that move up and down, and clamping components for holding the material tray are installed on the lifting components.

[0006] The material picker has two sets of guide plates symmetrically installed at its front and rear ends. A positioning structure for positioning the material tray is provided at the middle of the upper part of the guide plates. An unlocking mechanism for unlocking the positioning structure is installed inside the material picker. The unlocking mechanism is connected to two clamping parts on the left and right. A pushing mechanism for pushing the material tray is installed above the upper and lower material picker and the material picker.

[0007] Preferably, the lifting structure includes a lifting screw that rotates through a bearing seat and is vertically installed. The top end of the lifting screw is connected to the output shaft of the lifting motor via a coupling. Two sets of lifting guide rods are symmetrically arranged on the left and right sides of the lifting screw. Lifting components are slidably installed on the lifting guide rods. The lifting components are threadedly connected to the lifting screw via screw seats. The left and right lifting motors are controlled separately by two independent control power supplies and control systems. The lifting screw is installed on the rear side of the corresponding loading rack and unloading rack via a bearing seat, and the lifting motor is installed on the top of the corresponding loading rack and unloading rack via a motor frame.

[0008] Preferably, the lifting component has an opening in the middle, which is rectangular in shape. The length of the opening is greater than the length of the material tray, and the width of the opening is the same as the width of the material tray. A baffle is provided on the side of the lifting component away from the picking rack. The surface of the baffle facing the picking rack is flush with the inner wall of the opening of the lifting component away from the picking rack. This ensures that when the material tray is pushed to the left, it can contact the baffle in sequence to ensure that the material tray is pushed into place and can be accurately placed on the trolley below.

[0009] Preferably, the clamping component includes two clamping cylinders symmetrically fixed to the lifting component. A longitudinal plate is connected to the push rod of the clamping cylinder. The longitudinal plate is slidably installed above the lifting component via a rail. A clamping plate is fixed to the inward side of the longitudinal plate. An unlocking block is connected to the front clamping plate. The unlocking block is slidably installed on one of the rails. The unlocking block is connected to the clamping plate on the rail via a support plate.

[0010] When the two clamping plates move away from each other, the distance between them is greater than the length of the material tray. When the two clamping plates move inward towards each other under the action of the clamping cylinder, the clamping plates can lift the material tray, and the inner sidewall of the clamping plate contacts the support column below the material tray, which can restrict the forward and backward movement of the material tray.

[0011] Preferably, the guide plate has multiple linearly distributed circular holes extending vertically. The positioning structure includes a positioning rod that slides vertically into the circular holes. The top of the positioning rod is above the guide plate and is fixed with a positioning plate. A lifting block is fixed on the side of the positioning plate away from the material tray. The left and right sides of the lifting block are designed to form parallel contact slopes. The lifting block has a parallelogram structure. The bottom of the positioning rod is below the guide plate. A locking plate is fixed between the bottom ends of the front and rear positioning rods. A downward pressure spring is sleeved on the positioning rod. The two ends of the downward pressure spring abut against the locking plate and the guide plate, respectively. Under the action of the downward pressure spring, the positioning plate always has a downward tendency to move. The thickness of the positioning plate is the same as the depth of the positioning groove.

[0012] Lifting structures are also provided on the left and right sides above the guide plate. The distance between the left lifting structure and the positioning structure is the same as the distance between the right lifting structure and the positioning groove of the material tray on the feeding rack. The structure of the lifting structure is the same as the structure of the positioning structure. The length of the positioning plate in the lifting structure is less than the length of the positioning plate in the positioning structure. The positioning plate in the lifting structure will not contact or limit the material tray.

[0013] Preferably, two sets of guide sleeves symmetrically arranged front and back are welded to the lower left and right ends of the material picking rack. The unlocking mechanism includes a drive rod, which is slidably inserted into the two corresponding guide sleeves. The left end of the front drive rod and the right end of the rear drive rod are both fixed with abutment rings. An abutment spring is sleeved on the drive rod. The abutment spring abuts against the guide sleeve and the material picking rack. The abutment spring makes the drive rod always tend to move towards the corresponding unlocking block.

[0014] A limiting plate is fixed on the drive rod. The limiting plate has an L-shaped structure and faces the corresponding unlocking block. A locking notch is provided on the right front side and the left rear side of the locking plate. The limiting plate is engaged with the locking notch.

[0015] When locked, the limiting plate is engaged with the innermost side of the locking notch, and the upper lower surface of the limiting plate will contact the upper surface of the locking plate. The limiting plate will restrict the upward movement of the locking plate, thus preventing the positioning structure from unlocking.

[0016] When unlocking, the limiting plate moves away from the corresponding unlocking block, and the upper lower surface of the limiting plate is directly above the locking notch.

[0017] Preferably, the left end of the front drive rod and the right end of the rear drive rod are rotatably mounted with contact wheels via a pivot pin. The upper half of the unlocking block facing the contact wheel is cut off to form a pushing slope, and the lower half of the unlocking block facing the contact wheel forms a vertical unlocking surface.

[0018] When the lifting component is at its highest position, the contact wheel is in contact with the unlocking surface, the front drive rod moves to the right, the rear drive rod moves to the left, and the upper and lower surfaces of the limit plate are directly above the locking notch. At this time, the locking plate can move upward, the positioning plate can disengage from the positioning groove, and the pushing mechanism can push the material tray to move.

[0019] When the lifting component moves down and contacts or even disengages from the pushing ramp, the upper lower surface of the limiting plate contacts the upper surface of the locking plate. The limiting plate will restrict the upward movement of the locking plate. When the lifting component moves to the bottom, the contact wheel is still above the pushing ramp. This allows the contact wheel to still contact the pushing ramp and move horizontally when the lifting component moves up again.

[0020] When the lifting component does not move the clamping plate inward during the lifting process, the contact wheel does not contact the unlocking block, which also prevents the positioning structure from releasing the limit on the material tray, and the material tray cannot move.

[0021] Preferably, the pushing mechanism includes a movable lead screw rotatably mounted on the loading frame and the unloading frame via a bearing seat. The right end of the movable lead screw is connected to the output shaft of the moving motor via a coupling. Two sets of movable screw seats are threaded onto the movable lead screw. Two moving tracks are symmetrically distributed on the front and rear sides between the loading frame and the unloading frame. The movable screw seats are slidably connected to the two moving tracks. A pushing component is fixed at each of the front and rear ends of the movable screw seats.

[0022] Preferably, the pushing component includes a vertical rod fixed below the movable screw seat, a telescopic sleeve slidably connected to the vertical rod, a push block fixed below the telescopic sleeve on the side facing the material tray, both ends of the push block being inclined surfaces forming a push surface, a connecting frame fixed above the right side of the telescopic sleeve, and a push wheel rotatably mounted on the connecting frame via a shaft pin. Both the telescopic sleeve and the vertical rod have a convex cross-section, which allows the telescopic sleeve to slide up and down along the vertical rod.

[0023] The beneficial effects of this invention are:

[0024] 1. By setting up a loading rack, a picking rack, and a unloading rack, the loading rack and unloading rack can directly hold trolleys for loading trays. With the help of the pushing mechanism, lifting parts, and clamping parts, multiple stacked full-load trays in the loading rack can be continuously transported to the picking rack for subsequent capacitor processes. Empty trays can be directly stacked and placed into the trolley of the unloading rack. In capacitor production, there is no need for manual handling of trays, which reduces labor intensity. At the same time, it can also ensure that there are capacitors that can be grabbed and loaded in the picking rack, thus improving production efficiency.

[0025] 2. By setting a positioning structure on the picking rack, the positioning structure can position the fully loaded tray on the picking rack, so that it will not shift its position during the process of picking up capacitors, thereby improving the accuracy of capacitor picking and thus improving production efficiency.

[0026] 3. By setting two sets of unlocking mechanisms below the material picker, which are connected to the lifting components in the loading and unloading racks respectively, the material tray can only be pushed when the clamping components in the loading and unloading racks are at their highest positions. When the clamping components are at their highest positions but not clamping, the material tray will not move to the unloading rack for unloading, thus ensuring that the material tray is always on the clamping components and improving safety.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Referring to Figures 1-9, a conveying device for automotive capacitor production includes a loading rack 1, a unloading rack 3 on the left side of the loading rack 1, a trolley 4 placed inside both the loading rack 1 and the unloading rack 3, a material tray 5 placed on the trolley 4, positioning grooves on both the front and rear sides of the upper surface of the material tray 5, support columns at the four corners below the material tray 5, and slots for engaging the support columns at the four corners above the material tray 5. A picking rack 2 is provided between the loading rack 1 and the unloading rack 3. A lifting structure 6 is installed behind both the loading rack 1 and the unloading rack 3. A lifting component 61 is installed on the lifting structure 6, which moves up and down. A clamping component 62 for clamping the material tray 5 is installed on the lifting component 61.

[0039] The material picker 2 has two sets of guide plates 21 symmetrically installed at the front and rear ends inside. A positioning structure 7 for positioning the material tray 5 is set at the middle of the upper part of the guide plate 21. An unlocking mechanism 8 for unlocking the positioning structure 7 is installed inside the material picker 2. The unlocking mechanism 8 is connected to the two left and right clamping parts 62. A pushing mechanism 9 for pushing the material tray 5 is installed above the material picker 2 between the upper material picker 1, the lower material picker 3 and the material picker 2.

[0040] Referring to Figures 1-4, the lifting structure 6 includes a lifting screw 602 that rotates through a bearing seat and is vertically installed. The top end of the lifting screw 602 is connected to the output shaft of the lifting motor 601 through a coupling. Two sets of lifting guide rods 603 are symmetrically arranged on the left and right sides of the lifting screw 602. Lifting components 61 are slidably installed on the lifting guide rods 603. The lifting components 61 are threadedly connected to the lifting screw 602 through a screw seat. The two lifting motors 601 are controlled separately by two independent control power supplies and control systems. The lifting screw 602 is installed on the rear side of the corresponding loading rack 1 and unloading rack 3 through a bearing seat, and the lifting motor 601 is installed on the top of the corresponding loading rack 1 and unloading rack 3 through a motor frame.

[0041] Referring to Figure 4, the lifting component 61 has an opening in the middle. The opening of the lifting component 61 is rectangular. The length of the opening in the middle of the lifting component 61 is greater than the length of the material tray 5. The width of the opening in the middle of the lifting component 61 is the same as the width of the material tray 5. A baffle is provided on the side of the lifting component 61 away from the material picker 2. The surface of the baffle facing the material picker 2 is flush with the inner wall of the opening of the lifting component 61 away from the material picker 2. This allows the material tray 5 to contact the baffle when it is pushed to the left, thereby ensuring that the material tray 5 is pushed into place and can be accurately placed on the trolley 4 below.

[0042] Referring to Figures 3 and 4, the clamping component 62 includes two clamping cylinders 621 symmetrically fixed to the lifting component 61. The two clamping cylinders 621 are controlled by a closed-loop servo system. The position of the push rod in the clamping cylinder 621 is fed back in real time by a displacement sensor. The sensor data is processed by algorithms such as PID control and adaptive compensation to dynamically correct the opening of the servo valve or proportional valve to ensure that the two clamping cylinders 621 are synchronized. A longitudinal plate 622 is connected to the push rod of the clamping cylinder 621. The longitudinal plate 622 is slidably installed above the lifting component 61 via a rail. A clamping plate 623 is fixed to the inward side of the longitudinal plate 622. An unlocking block 624 is connected to the right front clamping plate 623 in the unloading rack 3 and the left rear clamping plate 623 in the loading rack 1. The unlocking block 624 is slidably installed on the rail and is connected to the clamping plate 623 on the corresponding rail via a support plate.

[0043] When the two clamping plates 623 move away from each other, the distance between them is greater than the length of the material tray 5. When the two clamping plates 623 move inward towards each other under the action of the clamping cylinder 621, the clamping plates 623 can lift the material tray 5, and the inner sidewall of the clamping plate 623 contacts the support column below the material tray 5, which can restrict the forward and backward movement of the material tray 5.

[0044] Referring to Figures 5-7, the guide plate 21 has multiple linearly distributed circular holes running vertically through it. The positioning structure 7 includes a positioning rod 707 that slides vertically into the circular holes. The top of the positioning rod 707 is above the guide plate 21 and is fixed to a positioning plate 701. A lifting block 702 is fixed to the side of the positioning plate 701 away from the material tray 5. The lifting block 702 has parallel contact slopes 703 on its left and right sides. The lifting block 702 has a parallelogram-shaped structure. The bottom end of 707 is located below the guide plate 21. A locking plate 705 is fixed between the bottom ends of the front and rear positioning rods 707. A lower compression spring 704 is sleeved on the positioning rod 707. The two ends of the lower compression spring 704 abut against the locking plate 705 and the guide plate 21 respectively. Under the action of the lower compression spring 704, the positioning plate 701 always has a downward tendency, so that the positioning plate 701 can be locked into the positioning groove of the material tray 5. The thickness of the positioning plate 701 is the same as the depth of the positioning groove.

[0045] Lifting structures 71 are also provided on the left and right sides above the guide plate 21. The distance between the left lifting structure 71 and the positioning structure 7 is the same as the distance between the right lifting structure 71 and the positioning groove of the material tray 5 on the feeding rack 1. The structure of the lifting structure 71 is the same as the structure of the positioning structure 7. The length of the positioning plate 701 in the lifting structure 71 is less than the length of the positioning plate 701 in the positioning structure 7. The positioning plate 701 in the lifting structure 71 will not contact or limit the material tray 5.

[0046] Referring to Figures 6 and 7, two sets of guide sleeves symmetrically arranged front and back are welded to the lower left and right ends of the material picker 2. The unlocking mechanism 8 includes a drive rod 81 that is slidably inserted into the guide sleeve. The left end of the front drive rod 81 and the right end of the rear drive rod 81 are both fixed with abutment rings 83. An abutment spring 82 is sleeved on the drive rod 81. The abutment spring 82 abuts against the guide sleeve and the material picker 2. The abutment spring 82 makes the drive rod 81 always have a tendency to move towards the corresponding unlocking block 624.

[0047] A limiting plate 85 is fixed on the drive rod 81. The limiting plate 85 has an L-shaped structure. A locking notch 706 is opened on the right front side and the left rear side of the locking plate 705. The limiting plate 85 is snapped into the locking notch 706 and the limiting plate 85 is hung on the locking plate 705.

[0048] When locked, the limiting plate 85 is engaged with the innermost side of the locking notch 706, and the upper part of the limiting plate 85 will be in contact with the upper surface of the locking plate 705. The limiting plate 85 will restrict the upward movement of the locking plate 705, thus preventing the positioning structure 7 from unlocking. That is, the positioning plate 701 cannot disengage from the positioning groove, and the material tray 5 cannot move. When unlocking, the limiting plate 85 moves away from the corresponding unlocking block 624, and the upper and lower surfaces of the limiting plate 85 are above the locking notch 706. At this time, the locking plate 705 can move upward, the positioning plate 701 can disengage from the positioning groove, and the pushing mechanism 9 can push the material tray 5 to move.

[0049] The left end of the front drive rod 81 and the right end of the rear drive rod 81 are rotatably mounted with a contact wheel 84 via a shaft pin. The upper half of the unlocking block 624 facing the contact wheel 84 has a portion removed to form a pushing slope 625, and the lower half of the unlocking block 624 facing the contact wheel 84 forms a vertical unlocking surface 626.

[0050] When the lifting component 61 is at its highest position, that is, the upper surface of the clamping plate 623 is flush with the upper surface of the guide plate 21, the empty material tray 5 can be directly moved to the top of the clamping plate 623 by the pushing mechanism 9. At this time, the contact wheel 84 is in contact with the unlocking surface 626, the front drive rod 81 moves to the right, the rear drive rod 81 moves to the left, the upper and lower surfaces of the limiting plate 85 are directly above the locking notch 706, the locking plate 705 can move upward, the positioning plate 701 can disengage from the positioning groove, and the pushing mechanism 9 can push the material tray 5 to move.

[0051] When the lifting member 61 moves down and contacts or even disengages from the pushing inclined surface 625, that is, when a height difference appears between the upper surface of the clamping plate 623 and the upper surface of the guide plate 21, the front drive rod 81 moves to the right under the action of the abutment spring 82, and the rear drive rod 81 moves to the left under the action of the abutment spring 82. The upper and lower surfaces of the limiting plate 85 contact the upper surface of the locking plate 705. The limiting plate 85 will restrict the upward movement of the locking plate 705. When the lifting member 61 moves to the bottom, the contact wheel 84 is still above the pushing inclined surface 625. This allows the contact wheel 84 to still contact the pushing inclined surface 625 and move horizontally when the lifting member 61 moves up again.

[0052] When the lifting component 61 does not move the clamping plate 623 inward during the lifting process, that is, the distance between the front and rear clamping plates 623 is too large to allow the material tray 5 to move horizontally above the clamping plate 623, the contact wheel 84 does not contact the unlocking block 624, which also prevents the positioning structure 7 from releasing the limit on the material tray 5, and the material tray 5 cannot move.

[0053] Referring to Figures 6-9, the pushing mechanism 9 includes a movable lead screw 93 rotatably mounted on the upper feed frame 1 and the lower feed frame 3 via a bearing seat. The right end of the movable lead screw 93 is connected to the output shaft of the movable motor 91 via a coupling. Two sets of movable screw seats 94 are threaded onto the movable lead screw 93. Two movable tracks 92 are symmetrically distributed on the front and rear sides between the upper feed frame 1 and the lower feed frame 3. The movable screw seats 94 are slidably connected to the two movable tracks 92. A pusher 95 is fixed at each of the front and rear ends of the movable screw seats 94.

[0054] The pusher 95 includes a vertical rod 951 fixed below the movable screw seat 94. The vertical rod 951 is slidably sleeved with a telescopic sleeve 952. A push block 953 is fixed below the telescopic sleeve 952 on the side facing the material tray 5. Both ends of the push block 953 are inclined surfaces, which form a push surface. A connecting frame 954 is fixed above the right side of the telescopic sleeve 952. A push wheel 955 is rotatably mounted on the connecting frame 954 through a shaft pin. The cross-sections of the telescopic sleeve 952 and the vertical rod 951 are both convex, which allows the telescopic sleeve 952 to slide up and down along the vertical rod 951. The distance between the lower surface of the connecting frame 954 and the upper surface of the push block 953 is greater than the thickness of the lifting block 702. This allows the pusher 95 to pass smoothly when moving to the left after the pusher 953 lifts the lifting block 702 upwards, and the lifting block 702 will not collide with the connecting frame 954 or the pusher 953.

[0055] When the moving screw 93 causes the moving screw seat 94 to move to the left, the pushing surface on the left side of the push block 953 will first contact the contact inclined surface 703 on the right side of the lifting block 702 and push the lifting block 702 to move upward. When the upper surface of the push block 953 contacts the lower surface of the lifting block 702, the positioning plate 701 will disengage from the positioning groove, and the push wheel 955 will contact the right surface of the material tray 5. At this time, the material tray 5 can be moved to the left above the two clamping plates 623 of the unloading rack 3, and the material tray 5 located on the loading rack 1 will be moved to the picking rack 2. The material tray 5 is in the original position of the material tray 5. The overall weight of the material tray 5 is relatively heavy, and its position will not shift during the translation process.

[0056] During the return journey, when the rightmost push block 953 and push wheel 955 move backward a certain distance, push block 953 disengages from the lifting block 702. At this time, the positioning plate 701 can be engaged in the positioning groove of the material tray 5 under the action of the lower pressure spring 704, thereby fixing the material tray 5 located on the material picker 2. When the two push blocks 953 contact the lifting blocks 702 on the two lifting structures 71 on the left and right sides, since the left side of the lifting block 702 is provided with the same contact slope 703 as the right side, and the right side of the push block 953 is also provided with the same push surface, when moving to the right, the push block 953 will move upward along the contact slope 703 of the lifting block 702, thereby enabling the telescopic sleeve 952 to drive the push wheel 955 to move upward together.

[0057] When the lower surface of the push block 953 contacts the upper surface of the lifting block 702 of the lifting structure 71, the push wheel 955 is just on the upper surface of the material tray 5. When the push wheel 955 is on the right side of the material tray 5, the push wheel 955 and the push block 953 fall back to their original positions under their own gravity. This allows the push wheel 955 to be placed directly on the right side of the corresponding material tray 5 when moving to the right in the future, and the position of the material tray 5 will not change during the return journey.

[0058] Working principle: Both the loading rack 1 and the unloading rack 3 are equipped with baffles. The baffles ensure that the material tray 5 on the trolley 4 is directly below the openings of the clamping component 62 and the lifting component 61. The trolley 4 has four slots that correspond one-to-one with the four support columns below the material tray 5. The material tray 5 is inserted into the slots through the support columns, thereby fixing the material tray 5. When multiple material trays 5 are stacked, there is a gap between two adjacent material trays 5.

[0059] Stack the trays 5 containing capacitors onto a trolley 4 and push the trolley 4 into the loading rack 1 on the right. Then move an empty trolley 4 into the unloading rack 3 on the left. At this time, the unlocking mechanism 8 in the unloading rack 3 releases the lock on the positioning structure 7.

[0060] The right-side lifting motor 601 rotates in the forward direction, and the lifting component 61 moves downward under the action of the lifting structure 6. During the downward movement, the two clamping cylinders 621 on the lifting component 61 move away from each other, and the distance between the two clamping plates 623 increases. When the lifting component 61 moves downward, it can directly move to the bottom of the uppermost material tray 5 of the right-side trolley 4, and make the clamping plate 623 in the gap between the two adjacent material trays 5. Then the push rod of the clamping cylinder 621 extends and makes the clamping plate 623 extend into the bottom of the uppermost material tray 5, and the clamping plate 623 contacts the support column below the material tray 5. When the two are in contact and can be subjected to a certain degree of force, they can slide.

[0061] Then the lifting motor 601 rotates in the opposite direction, and the lifting component 61 drives the material tray 5 to rise together under the action of the lifting structure 6. During the rising process, the pushing inclined surface 625 of the unlocking block 624 in the loading rack 1 will contact the contact wheel 84 and push the drive rod 81 to move away from the corresponding unlocking block 624. This causes the limiting plate 85 to move away from the corresponding unlocking block 624. When it moves to the highest position, the upper lower surface of the limiting plate 85 is directly above the locking notch 706. At this time, both the left and right limiting plates 85 release the locking plate 705, and the two clamping plates 623 on the right lifting component 61 are coplanar with the guide plate 21 and the two clamping plates 623 on the left lifting component 61.

[0062] Immediately afterward, the moving motor 91 rotates in the forward direction, causing the two moving screw seats 94 to move synchronously to the left. When the two moving screw seats 94 move synchronously to the left, the pushing component 95 located on the moving screw seat 94 will also move to the left along with it. The tray 5 with the full load of capacitors on the feeding rack 1 will be pushed to the left by the pushing component 95 on the right to the guide plate 21. During the pushing process to the left, since the left and right ends of the push block 953 are provided with inclined pushing surfaces, and the left and right ends of the lifting block 702 in the lifting structure 71 are also provided with contact inclined surfaces 703 with the same slope, the push block 953 in the right pushing component 95 will push the lifting block 702 in the right lifting structure 71 and move to the left side through the bottom of the lifting structure 71. During this process, the position of the push wheel 955 rises, so that the pushing component 95 can move smoothly to the left and push the full load tray 5 to the left.

[0063] When the fully loaded tray 5 approaches the middle of the upper part of the picking rack 2, the inclined surface of the push block 953 in the pusher 95 will contact the contact inclined surface 703 in the positioning structure 7 and push it to drive the positioning plate 701 to move upward together. When the fully loaded tray 5 is pushed into place, the positioning groove of the tray 5 is directly below the positioning plate 701. Then the pushing mechanism 9 returns to its original position to wait for the next push. After the push block 953 and push wheel 955 on the right move to the right a certain distance, the push block 953 disengages from the contact with the lifting block 702. At this time, the positioning plate 701 can be engaged in the positioning groove of the tray 5 under the action of the lower pressure spring 704, thereby fixing the tray 5 located on the picking rack 2. At this time, the capacitor on the tray 5 can be picked up by the external robot and sent to the required equipment for the corresponding process.

[0064] After the pusher 95 moves the full-load tray 5 on the loading rack 1 to the top of the picking rack 2, the lifting member 61 in the loading rack 1 moves down again and grabs the full-load tray 5 and returns to the top. The moving screw seat 94 and the pusher 95 in the pushing mechanism 9 return to their original positions after the pushing is completed. During the return process, when the two push blocks 953 on the left and right sides come into contact with the lifting blocks 702 on the two lifting structures 71 on the left and right sides, since the left side of the lifting block 702 is provided with the same contact slope 703 as the right side, and the right side of the push block 953 is also provided with the same pushing surface, when it continues to move to the right, the push block 953 will move upward along the contact slope 703 of the lifting block 702, so that the telescopic sleeve 952 can drive the push wheel 955 to move upward together.

[0065] Even if a fully loaded material tray 5 is added above the feeding rack 1, after the lower surface of the push block 953 contacts the upper surface of the lifting block 702 of the lifting structure 71, the push wheel 955 is just on the upper surface of the material tray 5. When the push wheel 955 is on the right side of the material tray 5, the push wheel 955 and the push block 953 fall back to their original positions under their own gravity. This allows the push wheel 955 to be placed directly on the right side of the corresponding material tray 5 when moving to the right in the future, so as to facilitate the next push.

[0066] After the capacitor is picked up on the picking rack 2, since the lifting components 61 in the unloading rack 3 and the loading rack 1 are at their highest positions, the unlocking mechanisms 8 in the loading rack 1 and the unloading rack 3 release the lock on the positioning structure 7. The moving motor 91 causes the two moving screw seats 94 to drive the pushing component 95 below them to move to the left again. As with the above operation, the empty tray 5 will move to the clamping component 62 on the left unloading rack 3, while the full tray 5 will be moved back to the picking rack 2. During the return process, the full tray 5 will be positioned again. Then, the lifting components 61 in the loading rack 1 and the unloading rack 3 will drive the clamping component 62 to move downward. The clamping component 62 in the loading rack 1 will pick up the full tray 5 again, while the clamping component 62 in the unloading rack 3 will lower the empty tray 5 onto the empty trolley 4. In the subsequent placement, multiple empty trays 5 will be stacked. This operation can be repeated to continuously move the trays 5.

[0067] By setting up a loading rack 1, a picking rack 2, and a unloading rack 3, the trolley 4 for loading trays 5 can be directly placed in the loading rack 1 and the unloading rack 3. With the help of the pushing mechanism 9, lifting parts 61, and clamping parts 62, multiple stacked full-load trays 5 in the loading rack 1 can be continuously transported to the picking rack 2 for subsequent capacitor processes. Empty trays 5 can be directly stacked and placed in the trolley 4 of the unloading rack 3. In capacitor production, there is no need for manual handling of trays 5, which reduces labor intensity. At the same time, it can also ensure that there are capacitors that can be grabbed and loaded in the picking rack 2, which improves production efficiency.

[0068] By setting a positioning structure 7 on the picking rack 2, the positioning structure 7 can position the fully loaded tray 5 on the picking rack 2, so that it will not shift its position during the process of picking up capacitors, thereby improving the accuracy of capacitor picking and thus improving production efficiency.

[0069] By setting two sets of unlocking mechanisms 8 below the material picker 2, and connecting the two sets of unlocking mechanisms 8 to the lifting parts 61 of the upper material picker 1 and the lower material picker 3 respectively, the material tray 5 can only be pushed when the clamping parts 62 in the upper material picker 1 and the lower material picker 3 are at the top. When the clamping parts 62 are at the top but not clamping, the material tray 5 will not move to the lower material picker 3 for unloading, thus ensuring that the material tray 5 can always be on the clamping parts 62, improving safety.
