However, traditional loading carts often cannot accurately dock at preset positions, and the positioning accuracy of loading carts needs to be improved.

[0004] Summary of the Invention

[0005] In view of this, an embodiment of the present application provides a trolley positioning device and a battery manufacturing device, which can improve the positioning accuracy of the loading trolley.

[0006] The embodiment of the first aspect of the present application provides a trolley positioning device, comprising:

[0007] loading trolley;

[0008] The positioning device includes a guide structure and a positioning structure. The guide structure is used to guide the loading trolley so that the loading trolley moves along the guide structure; the positioning structure is used to fix the loading trolley.

[0009] The trolley positioning device provided in an embodiment of the present application includes a loading trolley and a positioning device. The positioning device includes a guide structure and a positioning structure. The guide structure can guide the loading trolley so that the loading trolley moves along the guide structure. In this way, the loading trolley can move along a preset path, thereby improving the movement accuracy of the loading trolley. In addition, the positioning structure can fix the loading trolley after the loading trolley moves to a preset position, so that the loading trolley stops at the preset position. Therefore, the above-mentioned trolley positioning device can guide and position the loading trolley, improve the positioning accuracy of the loading trolley, and enable the loading trolley to accurately stop at the preset position, which is conducive to accurate operation of items on the loading trolley.

[0010] In some embodiments, the guide structure extends along a first direction, and the positioning structure includes a positioning bracket and a precision positioning member provided on the positioning bracket; a positioning fitting member is provided on the loading trolley, and the precision positioning member is used to engage with the positioning fitting member.

[0011] The positioning structure provided in the embodiment of the present application includes a positioning bracket and a precision positioning part. The positioning bracket can stop the loading trolley, and the precision positioning part can be engaged with the positioning matching part on the loading trolley, so that the positioning structure can fine-tune the position of the loading trolley. The positioning structure plays a role of precision positioning, further improving the positioning accuracy of the loading trolley.

[0012] In some embodiments, one of the precision positioning part and the positioning matching part is provided with a recessed slot along one side of the first direction, and the other of the precision positioning part and the positioning matching part is provided with a retaining protrusion along one side of the first direction, and the retaining protrusion can be interlocked with the retaining slot.

[0013] By adopting the above technical solution, when the loading trolley moves to the positioning bracket, the holding protrusion on the positioning matching part and the card groove in the fine positioning part engage with each other, which can not only realize the position correction of the loading trolley, but also fix the loading trolley.

[0014] In some embodiments, the slot includes two guide walls and a bottom wall connecting the two guide walls. The two guide walls are arranged opposite to each other along a second direction and are respectively connected to the bottom wall at an angle. The second direction intersects with the first direction, and the width of the slot gradually decreases along the first direction toward away from the positioning fitting.

[0015] By adopting the above technical solution, as the retaining protrusion gradually inserts into the retaining slot, the two guide walls of the retaining slot can guide the positioning member, allowing the positioning member to be fine-tuned in the second direction, thereby fine-tuning the position of the loading trolley in the second direction. Therefore, the above-mentioned precise positioning member can not only limit the loading trolley in the direction of travel, but also calibrate the position of the loading trolley in the second direction, achieving a precise alignment effect and further improving the positioning accuracy of the loading trolley.

[0016] In some embodiments, the guide structure includes two guide bars that are opposite and spaced apart, and the guide bars extend along the first direction, and a guide gap extending along the first direction is formed between the two guide bars; a guide fitting is provided at the bottom of the loading trolley, and the guide fitting can slide in the guide gap.

[0017] By adopting the above technical solution, the guide structure can use two guide bars to guide the guide matching parts at the bottom of the loading trolley, which is conducive to the loading trolley reaching the accurate preset position, and the guide structure has the advantages of simple structure and easy implementation.

[0018] In some embodiments, the guide fitting is a locating bearing.

[0019] The guide fitting provided in the embodiment of the present application is a positioning bearing, which can slide smoothly between the two guide bars. The guide structure cooperates with the guide fitting, which can guide the loading trolley without generating large friction on the loading trolley, thereby facilitating the loading trolley to move smoothly to the preset position.

[0020] In some embodiments, the guide bar is provided with an arcuate guide surface on the side facing the guide gap, and the arcuate guide surface is located at the end of the guide bar away from the precision positioning part; along the first direction pointing to the direction of the precision positioning part, the distance between the two arcuate guide surfaces gradually becomes smaller.

[0021] By adopting the above technical solution, an arc-shaped guide surface is provided at the end of the guide structure, which can guide the guide fitting to smoothly enter the guide gap to adjust the travel direction of the loading trolley, so that the loading trolley can reach the preset position along the guide structure, thereby improving the movement accuracy and positioning accuracy of the loading trolley.

[0022] In some embodiments, the positioning structure also includes a positioning drive member provided on the positioning bracket and a push member connected to the positioning drive member, and the positioning drive member is used to drive the push member to move, so that the push member applies force to the loading trolley, thereby fixing the loading trolley to the positioning bracket.

[0023] The positioning structure provided in the embodiment of the present application includes a positioning drive member and a push member. The positioning drive member can drive the push member to move, so that the loading trolley is fixedly fitted to the positioning bracket, and can fix the loading trolley at the positioning bracket to prevent the loading trolley from shifting or shaking.

[0024] In some embodiments, one end of the ejection member is rotatably connected to the positioning drive member, and the other end is a free end for pushing the loading trolley; the positioning drive member is used to drive the ejection member to rotate so that the free end swings and pushes the loading trolley.

[0025] By adopting the above technical solution, the ejector can be rotated to fix the loading trolley and avoid the loading trolley, which is easy to use.

[0026] In some embodiments, a sensor is provided on the positioning bracket, and the sensor is used to sense the loading trolley and send out a sensing signal, and the positioning driving member drives the ejecting member to move according to the sensing signal.

[0027] By setting up sensors, the positioning drive can timely control the ejection parts to fix the loading trolley, thereby improving the positioning efficiency.

[0028] In some embodiments, the positioning structure includes a limiting member, and a limiting fitting member is provided at the bottom of the loading trolley, and the limiting member is used to clamp the limiting fitting member to fix the loading trolley at a preset position.

[0029] By adopting the above technical solution, the limiting member can clamp the limiting matching member to fix the loading trolley at a preset position, thereby achieving accurate positioning of the loading trolley.

[0030] In some embodiments, the side of the limiting fitting facing the limiting member has an inclined guide surface and a holding surface connected along a first direction, the height of the inclined guide surface gradually decreases from the end away from the holding surface toward the direction close to the holding surface, and the height of the holding surface is lower than the height of the inclined guide surface; the limiting member can enter the holding surface along the inclined guide surface and abut against the holding surface.

[0031] By adopting the above technical solution, an inclined guide surface and a holding surface are provided on the limiting fitting, and the limiting fitting can be held against the holding surface to prevent the loading trolley from continuing to move, so that the loading trolley is accurately positioned, thereby improving the positioning accuracy of the loading trolley.

[0032] In some embodiments, the limiting member includes a mounting member and a universal ball bull's eye bearing provided on the mounting member, and the universal ball bull's eye bearing is used to support and position the limiting fitting member.

[0033] By adopting the above technical solution, the universal ball bull's eye bearing can support and position the limit fitting, and the friction between the universal ball bull's eye bearing and the inclined guide surface is small, which enables the carrying trolley to slide smoothly above the universal ball bull's eye bearing until the highest point of the universal ball bull's eye bearing is tightly in contact with the abutment surface, thereby achieving the purpose of positioning.

[0034] In some embodiments, there are multiple limit members and multiple limit fitting members, the vertices of multiple universal ball bull's eye bearings are located in the same horizontal plane and are not completely on the same straight line, and the multiple universal ball bull's eye bearings jointly support the loading trolley.

[0035] The above-mentioned trolley positioning device not only uses multiple limit members to accurately position the loading trolley, but also can keep the loading trolley level, thereby realizing the function of horizontal correction.

[0036] In some embodiments, the guide structure is provided with two of the limit members on both sides along the second direction, and the two limit members on each side are arranged at intervals along the first direction; the loading trolley is provided with two of the limit fitting members on both sides along the second direction, and the two limit fitting members on each side are arranged at intervals along the first direction.

[0037] In some embodiments, some of the limiting members further include a gasket, which is detachably disposed between the mounting member and the universal ball bull's eye bearing, and is used to increase the height of the universal ball bull's eye bearing.

[0038] By adopting the above technical solution and arranging washers in a plurality of limiting members, the vertices of a plurality of universal ball bull's eye bearings can be made flush and in the same horizontal plane.

[0039] In some embodiments, the limiting fitting part further has a limiting surface on the side facing the limiting part, the holding surface and the inclined guide surface are arranged on the same side of the limiting surface, the second direction intersects with the first direction, and the inclined guide surface is recessed relative to the limiting surface.

[0040] By adopting the above technical solution, a groove is formed on the inclined guide surface on the limiting fitting. When the loading trolley moves on the limiting fitting, the universal ball bull's eye bearing can slide relative to the inclined guide surface and is not easily offset, thereby further improving the accuracy of the loading trolley's movement.

[0062] Loading carts are widely used in various manufacturing equipment. For example, battery manufacturing equipment requires them to load batteries. However, traditional loading carts are often manually positioned and cannot be accurately docked at the preset position. Subsequent robotic grasping of items on the loading cart is prone to misgrabbing or even missing items. Therefore, the positioning accuracy of loading carts needs to be improved.

[0063] In order to solve the above problems, after in-depth research, a trolley positioning device of the trolley positioning equipment was designed. The trolley positioning device of the trolley positioning equipment includes a loading trolley and a positioning device, and the positioning device includes a guide structure and a positioning structure. The trolley positioning device of the trolley positioning equipment provided in the embodiment of the present application uses a guide structure to guide the movement of the loading trolley, which is conducive to the loading trolley reaching the preset position according to the predetermined route. The trolley positioning device of the trolley positioning equipment uses the positioning structure to position the loading trolley, which can accurately position the loading trolley at the preset position. In this way, the trolley positioning device of the trolley positioning equipment improves the positioning accuracy of the loading trolley, and can enable the loading trolley to be accurately docked at the preset position.

[0064] Please refer to Figures 1 and 2. An embodiment of the first aspect of the present application provides a trolley positioning device 100, including a loading trolley 10 and a positioning device 20. The positioning device 20 includes a guide structure 21 and a positioning structure 22. The guide structure 21 is used to guide the loading trolley 10 so that the loading trolley 10 moves along the guide structure 21; the positioning structure 22 is used to fix the loading trolley 10.

[0065] The loading trolley 10 is a trolley for loading articles. The loading trolley 10 may be a manual trolley, but is not limited thereto. The loading trolley 10 may also be an automatic trolley, such as an AGV trolley.

[0066] The positioning device 20 is fixed to a preset station and can locate the loading cart 10 when it reaches the preset station. The "preset station" is a station set according to production requirements and determines the preset position for the loading cart 10. When the loading cart 10 reaches the preset position, items on the loading cart 10 can be grabbed or other operations can be performed.

[0067] The positioning device 20 includes a guide structure 21 and a positioning structure 22, both of which are fixedly located at a predetermined position. The guide structure 21 is used to guide the loading trolley 10, causing the loading trolley 10 to move along the guide structure 21. The guide structure 21 extends in a first direction. In this embodiment, the first direction is the X direction. By guiding the direction of the loading trolley 10's travel path, the loading trolley 10 is facilitated to accurately reach the predetermined position. The guide structure 21 can include various guiding elements such as guide rails and guide plates.

[0068] The positioning structure 22 is used to fix the loading trolley 10 so that the loading trolley 10 can be accurately parked at a preset position. The positioning structure 22 can include various structures that can fix the loading trolley 10, such as positioning members, clamping members, and magnetic members.

[0069] When in use, the loading trolley 10 reaches the area where the positioning device 20 is located, and the loading trolley 10 moves along the guide structure 21 under the guidance of the guide structure 21 until the loading trolley 10 is positioned and fixed by the positioning structure 22. The loading trolley 10 can stay at the work station where the positioning device 20 is located.

[0070] The trolley positioning device 100 provided in the embodiment of the present application includes a loading trolley 10 and a positioning device 20. The positioning device 20 includes a guide structure 21 and a positioning structure 22. The guide structure 21 can guide the loading trolley 10 so that the loading trolley 10 moves along the guide structure 21. In this way, the loading trolley 10 can move along a preset path, thereby improving the movement accuracy of the loading trolley 10. In addition, the positioning structure 22 can fix the loading trolley 10 after the loading trolley 10 moves to a preset position, so that the loading trolley 10 stops at the preset position. Therefore, the above-mentioned trolley positioning device 100 can guide and position the loading trolley 10, improve the positioning accuracy of the loading trolley 10, and enable the loading trolley 10 to accurately stop at the preset position, which is conducive to accurate operation of items on the loading trolley 10.

[0071] Please refer to Figures 1 to 5. In some embodiments, the guide structure 21 extends along the first direction X, and the positioning structure 22 includes a positioning bracket 221 and a precision positioning member 222 provided on the positioning bracket 221; a positioning fitting member 15 is provided on the loading trolley 10, and the precision positioning member 222 is used to engage with the positioning fitting member 15.

[0072] Optionally, the positioning bracket 221 and the fine positioning member 222 are provided on one side of the guide structure 21 along the first direction X. It will be understood that the guide structure 21 includes a head end and a tail end provided along the first direction X, and the loading trolley 10 can move from the head end to the tail end when traveling along the first direction X. In other embodiments, the positioning bracket 221 and the fine positioning member 222 can also be provided on one side or both sides of the loading trolley along the second direction Y.

[0073] The positioning bracket 221 and the fine positioning member 222 are used to stop and position the loading trolley 10. The positioning bracket 221 is arranged on one side of the guide structure 21 along the first direction X. In this way, when the loading trolley 10 moves along the guide structure 21 to a preset position, the loading trolley 10 can fit on the positioning bracket 221, so that the positioning bracket 221 can stop the loading trolley 10. The fine positioning member 222 can be fixed to the positioning bracket 221. It is understood that if the positioning position of the loading trolley 10 needs to be adjusted, the fine positioning member 222 can also be movably arranged on the positioning bracket 221; the positioning fitting member 15 can be arranged at the bottom of the loading trolley 10, but is not limited to this. The positioning fitting member 15 can also be arranged in the middle or top of the loading trolley 10.

[0074] The precision positioning part 222 and the positioning matching part 15 can engage with each other, so that the precision positioning part 222 can correct the position of the loading cart 10 and fine-tune the position of the loading cart 10, and the precision positioning part 222 can also fix the loading cart 10. After the precision positioning part 222 and the positioning matching part 15 engage with each other, the loading cart 10 is not easy to shift left and right.

[0075] The positioning structure 22 provided in the embodiment of the present application includes a positioning bracket 221 and a fine positioning member 222. The guide structure 21 can guide the loading cart 10 to move along the first direction X, and the guide structure 21 plays a role of rough positioning; the positioning bracket 221 can stop the loading cart 10, and the fine positioning member 222 can engage with the positioning matching member 15 on the loading cart 10, so that the positioning structure 22 fine-tunes the position of the loading cart 10, and the positioning structure 22 plays a role of fine positioning, further improving the positioning accuracy of the loading cart 10.

[0076] Please refer to Figures 3, 5 and 7. In some embodiments, one of the precision positioning member 222 and the positioning matching member 15 is provided with a recessed slot 2221 on one side along the first direction X, and the other of the precision positioning member 222 and the positioning matching member 15 is provided with a holding protrusion 151 on one side along the first direction X, and the holding protrusion 151 can be engaged with the slot 2221.

[0077] A slot 2221 is provided in the precision positioning member 222, and the notch of the slot 2221 is provided on the side of the precision positioning member 222 facing the guide structure 21 along the first direction X; the shape of the slot 2221 can be square, trapezoidal, triangular, etc.; the holding protrusion 151 on the positioning matching member 15 is adapted to the shape and size of the slot 2221 so that the holding protrusion 151 can be held in the slot 2221.

[0078] When the loading trolley 10 moves to the positioning bracket 221 , the holding protrusion 151 on the positioning fitting 15 and the locking groove 2221 in the precision positioning part 222 engage with each other, which can realize the position correction of the loading trolley 10 and improve the positioning accuracy of the loading trolley 10 .

[0079] In other embodiments, the precision positioning member 222 and the positioning fitting member 15 are not limited to being mutually clamped along the first direction X. For example, the two may be mutually clamped in the vertical direction (third direction Z) or in the second direction Y.

[0080] 5 , in some embodiments, the slot 2221 includes two guide walls 22211 and a bottom wall 22212 connecting the two guide walls 22211 . The two guide walls 22211 are arranged opposite to each other along a second direction Y and are obliquely connected to the bottom wall 22212 , respectively. The second direction Y intersects with the first direction X.

[0081] The extension direction of the guide wall 22211 is inclined to the first direction X and the second direction Y, and the width of the slot 2221 gradually decreases along the first direction toward the direction away from the positioning fitting 15, so that the slot 2221 is roughly trapezoidal or dovetail-shaped; accordingly, the width of the holding protrusion 151 gradually decreases along the direction approaching the positioning bracket 221.

[0082] When the loading trolley 10 moves toward the positioning bracket 221 , the end of the holding protrusion 151 is inserted into the slot 2221 . Under the guidance of the two guide walls 22211 , the holding protrusion 151 is gradually inserted into the slot 2221 and the slots 2221 are engaged.

[0083] Optionally, the slot 2221 is provided on the precision positioning member 222 , and the holding protrusion 151 is provided on the positioning fitting member 15 ; in other embodiments, the slot 2221 may also be provided on the positioning fitting member 15 and the holding protrusion 151 may also be provided on the precision positioning member 222 .

[0084] By adopting the above technical solution, as the retaining protrusion 151 is gradually inserted into the retaining slot 2221, the two guide walls 22211 of the retaining slot 2221 can guide the positioning fitting 15, allowing the position of the positioning fitting 15 in the second direction Y to be fine-tuned, thereby fine-tuning the position of the loading trolley 10 in the second direction Y. Therefore, the above-mentioned fine positioning member 222 can not only limit the loading trolley 10 in the direction of travel of the loading trolley 10 (the first direction X), but also calibrate the position of the loading trolley 10 in the second direction Y, achieving a precise alignment effect and further improving the positioning accuracy of the loading trolley 10.

[0085] Referring to Figures 3, 4 and 6, in some embodiments, the guide structure 21 includes two guide bars 211 that are opposite and spaced apart, and the guide bars 211 extend along the first direction X. A guide gap 212 extending along the first direction X is formed between the two guide bars 211; a guide fitting 14 is provided at the bottom of the loading trolley 10, and the guide fitting 14 can slide within the guide gap 212.

[0086] The two guide bars 211 are arranged opposite to each other and spaced apart along the second direction Y. The guide gap 212 formed between the two guide bars 211 is used for the sliding of the guide fitting 14 at the bottom of the loading trolley 10. In this way, the guide structure 21 can guide the movement of the loading trolley 10, which is conducive to the loading trolley 10 accurately reaching the preset position.

[0087] The guide structure 21 can be fixed on the ground, or fixed on a fixed foundation such as a bottom plate 213. Optionally, both guide bars 211 are provided on the bottom plate 213, which is fixed on the ground to fix the position of the guide structure 21.

[0088] By adopting the above technical solution, the guide structure 21 can use two guide bars 211 to guide the guide matching part 14 at the bottom of the loading trolley 10, which is conducive to the loading trolley 10 reaching the accurate preset position, and the guide structure 21 has the advantages of simple structure and easy implementation.

[0089] In other embodiments, the guide structure 21 is not limited thereto. For example, the guide structure 21 may also include a limiting guide rail for limiting the side of the loading trolley 10 , as long as the guide structure 21 can guide the loading trolley 10 .

[0090] In some embodiments, the guide fitting 14 is a locating bearing.

[0091] Locating bearings, also known as fixed bearings, are a type of bearing in mechanical engineering that is axially fixed and does not allow for axial movement. These bearings are primarily used to precisely locate and maintain a shaft in a machine or device, ensuring accurate and reliable axial positioning. They are typically secured to the shaft using adapter sleeves, screws, or other means to prevent axial movement during operation.

[0092] Optionally, the outer diameter of the locating bearing is adapted to the width of the guide gap 212 , so that the locating bearing can slide against the folding guide strip 211 .

[0093] The guide fitting 14 provided in the embodiment of the present application is a positioning bearing, which can slide smoothly between the two guide bars 211. The guide structure 21 cooperates with the guide fitting 14, which can guide the loading trolley 10 without generating large friction on the loading trolley 10, which is conducive to the smooth movement of the loading trolley 10 to the preset position.

[0094] In other embodiments, the precise positioning member 222 may also be other structures, for example, the precise positioning member 222 may also be a universal ball, a positioning block, or other structures.

[0095] Please continue to refer to Figures 3, 4 and 6. In some embodiments, an arcuate guide surface 2111 is provided on the side of the guide bar 211 facing the guide gap 212, and the arcuate guide surface 2111 is located at the end of the guide bar 211 away from the precision positioning member 222; along the first direction X pointing to the direction of the precision positioning member 222, the distance between the two arcuate guide surfaces 2111 gradually becomes smaller.

[0096] It will be appreciated that the arcuate guide surface 2111 is located on the side of the guide bar 211 away from the preset position of the loading cart 10. That is, the guide fitting 14 of the loading cart 10 first contacts the arcuate guide surface 2111 and then moves along the guide bar 211. The two arcuate guide surfaces 2111 form a bell-mouth shape at the head end of the guide structure 21, which can guide the guide fitting 14 into the guide gap 212 to adjust the travel direction of the loading cart 10.

[0097] By adopting the above-mentioned technical solution, an arc-shaped guide surface 2111 is provided at the end of the guide structure 21, which can guide the guide fitting 14 to smoothly enter the guide gap 212 to adjust the moving direction of the loading trolley 10, so that the loading trolley 10 reaches a preset position along the guide structure 21, thereby improving the movement accuracy and positioning accuracy of the loading trolley 10.

[0098] 3 and 6 , in some embodiments, the number of the guide fittings 14 is at least two, and the at least two guide fittings 14 are spaced apart along the first direction X.

[0099] In this embodiment, the number of the guide fittings 14 is two, and the two guide fittings 14 are spaced apart along the first direction X at the bottom of the loading trolley 10 .

[0100] By providing a plurality of guide fittings 14 , the loading trolley 10 can move along the guide structure 21 under the cooperation of the guide fittings 14 and the guide structure 21 , thereby improving the guide accuracy.

[0101] In other embodiments, the number of the guide fittings 14 may also be one, or more than two.

[0102] Please refer to Figures 1 to 5. In some embodiments, the positioning structure 22 also includes a positioning driving member 223 provided on the positioning bracket 221 and a pushing member 224 connected to the positioning driving member 223. The positioning driving member 223 is used to drive the pushing member 224 to move, so that the pushing member 224 applies force to the loading trolley 10, thereby fixing the loading trolley 10 to the positioning bracket 221.

[0103] The positioning driving member 223 may include a cylinder, or may include other mechanisms capable of driving the ejecting member 224 to move; the ejecting member 224 may be in various shapes such as a block or a column.

[0104] When the loading trolley 10 moves to the preset position, the fine positioning member 222 engages the positioning fitting 15; at this time, the positioning drive member 223 drives the ejecting member 224 to move toward the loading trolley 10. The ejecting member 224 applies force to the loading trolley 10, thereby securing the loading trolley 10 against the positioning bracket 221. In this way, the ejecting member 224 can play a holding role and prevent the loading trolley 10 from shifting. When the loading trolley 10 needs to be moved, the positioning drive member 223 drives the ejecting member 224 away from the loading trolley 10, thereby releasing the securing effect on the loading trolley 10.

[0105] Optionally, the pushing member 224 can push the crossbeam at the bottom of the loading trolley 10 so that the crossbeam fits the positioning bracket 221 ; it is understandable that the pushing member 224 can also push other parts of the loading trolley 10 so that the loading trolley 10 fits the positioning bracket 221 .

[0106] Optionally, multiple groups of ejecting members 224 may be provided and located on opposite sides of the loading trolley 10 , so that the oppositely arranged ejecting members 224 can jointly clamp the loading trolley 10 and the positioning bracket 221 .

[0107] The positioning structure 22 provided in the embodiment of the present application includes a positioning drive member 223 and a push member 224. The positioning drive member 223 can drive the push member 224 to move, so that the loading trolley 10 is fixedly attached to the positioning bracket 221, and can fix the loading trolley 10 at the positioning bracket 221 to prevent the loading trolley 10 from shifting or shaking.

[0108] 1 to 5 , in some embodiments, one end of the ejecting member 224 is rotatably connected to the positioning drive member 223 , and the other end is a free end for ejecting the loading cart 10 ; the positioning drive member 223 is used to drive the ejecting member 224 to rotate so that the free end swings and ejects the loading cart 10 .

[0109] The positioning drive 223 may include a cylinder and a connecting rod structure connected to the cylinder. The positioning drive 223 drives one end of the ejector 224 to rotate, thereby causing the free end to swing up and down. When the loading cart 10 needs to be secured, the positioning drive 223 drives the ejector 224 to rotate downward, allowing the bottom of the loading cart 10 to maintain contact with the positioning bracket 221. When the loading cart 10 needs to be removed, the positioning drive 223 drives the ejector 224 to rotate upward, allowing the free end of the ejector 224 to move away from the loading cart 10 and out of the way.

[0110] By adopting the above technical solution, the ejector 224 can be rotated to fix the loading trolley 10 and avoid the loading trolley 10, which is convenient to use.

[0111] In some embodiments, a sensor 225 is provided on the positioning bracket 221 . The sensor 225 is used to sense the loading trolley 10 and send out a sensing signal. The positioning driving member 223 drives the ejecting member 224 to move according to the sensing signal.

[0112] The sensor 225 is used to sense the loading cart 10 to detect whether the loading cart 10 has reached a predetermined position. The sensor 225 can be a proximity sensor, an infrared distance sensor, an ultrasonic sensor, an image recognition sensor, a radio frequency identification sensor, or the like. Upon sensing the loading cart 10, the sensor 225 emits a sensing signal. The positioning driver 223 activates the ejector 224 based on the sensing signal, thereby securing the loading cart 10.

[0113] By providing the sensor 225 , the positioning driving member 223 can timely control the pushing member 224 to fix the loading trolley 10 , thereby improving the positioning efficiency.

[0114] Please refer to Figures 1, 3, 4, 7 and 8. In some embodiments, the positioning device 20 also includes a limit member 226. A limit fitting member 13 is provided at the bottom of the loading trolley 10. The limit member 226 is used to clamp the limit fitting member 13 to fix the loading trolley 10 at a preset position.

[0115] The stopper 226 can be disposed on the bottom plate 213 of the guide structure 21. Thus, when the loading cart 10 moves along the guide structure 21 to a predetermined position, it is directly restrained by the stopper 226. It is understood that the stopper 226 can also be fixed to the ground or other fixed foundation. The stopper 13 is disposed at the bottom of the loading cart 10. The bottom of the loading cart 10 refers to the portion of the loading cart 10 that is located at the bottom when the loading cart 10 is normally positioned and moving.

[0116] When the loading trolley 10 moves to a preset position, the position-limiting member 226 is used to engage the position-limiting member 13 at the bottom of the loading trolley 10 to position the loading trolley 10. The position-limiting member 226 can have various structures, such as a positioning block, a positioning pin, a universal ball-and-eye bearing 2262, etc. The structure of the position-limiting member 13 is compatible with the position-limiting member 226, so that the position-limiting member 226 can engage the position-limiting member 13.

[0117] During use, before the loading trolley 10 moves to the preset position, the limit member 226 does not play a clamping role, so as to prevent the limit member 226 from hindering the movement of the loading trolley 10; when the loading trolley 10 moves to the preset position, the limit fitting member 13 moves to the limit member 226, and the limit fitting member 226 and the limit fitting member 13 clamp each other to prevent the loading trolley 10 from continuing to move, so that the loading trolley 10 can be docked at the preset position.

[0118] By adopting the above technical solution, the limiting member 226 can clamp the limiting fitting member 13 to fix the loading trolley 10 at a preset position, thereby achieving accurate positioning of the loading trolley 10.

[0119] Since both the limiting member 226 and the precise positioning member 222 can position the loading cart 10 , the positioning structure 22 may include only one of the limiting member 226 and the precise positioning member 222 , or may include both of them.

[0120] Please refer to Figures 2, 3, 7 and 8. In some embodiments, the side of the limiting fitting 13 facing the limiting member 226 has an inclined guide surface 131 and a clamping surface 132 connected along the first direction X, and the height of the inclined guide surface 131 gradually decreases from the end away from the clamping surface 132 toward the direction close to the clamping surface 132, and the height of the clamping surface 132 is lower than the height of the inclined guide surface 131; the limiting member 226 can enter the clamping surface 132 along the inclined guide surface 131 and abut against the clamping surface 132.

[0121] The first direction X is the extension direction of the guide structure 21 and is also the movement direction of the loading cart 10. The extension direction of the inclined guide surface 131 is inclined relative to the first direction X, and the inclined guide surface 131 is inclined relative to the stop member 226. The height of the inclined guide surface 131 gradually decreases from the end away from the retaining surface 132 toward the end closer to the retaining surface 132. The height of the inclined guide surface 131 refers to the height of the inclined guide surface 131 in the vertical direction (third direction Z).

[0122] When the loading cart 10 moves along the first direction X, the stopper 226 first contacts the inclined guide surface 131 and then contacts the retaining surface 132. That is, the inclined guide surface 131 slides relative to the stopper 226 until the stopper 226 abuts the retaining surface 132. The loading cart 10 is then positioned and no longer moves. In this way, each time the loading cart 10 moves to the positioning structure 22, the position of the loading cart 10 is precisely fixed. Compared to manually determining the docking position, the above-mentioned cart positioning device 100 improves the positioning accuracy of the loading cart 10.

[0123] By adopting the above technical solution, an inclined guide surface 131 and a holding surface 132 are provided on the limiting fitting 13, and the limiting member 226 can be abutted against the holding surface 132 to prevent the loading trolley 10 from continuing to move, so that the loading trolley 10 is accurately positioned, thereby improving the positioning accuracy of the loading trolley 10.

[0124] In other embodiments, the structure of the limiting fitting 13 is not limited thereto. For example, a slot 2221 is provided on the side of the limiting fitting 13 facing the limiting member 226 , and the limiting member 226 can be engaged with the slot 2221 to achieve positioning of the loading trolley 10 .

[0125] 2 to 8 , in some embodiments, the position-limiting member 226 includes a mounting member 2261 and a universal ball-bull's-eye bearing 2262 disposed on the mounting member 2261 . The universal ball-bull's-eye bearing 2262 is used to support and position the position-limiting fitting 13 .

[0126] The mounting member 2261 can be fixed on the guide structure 21 or on a fixed foundation such as the ground. The mounting member 2261 is used to mount the universal ball bull's eye bearing 2262. The mounting member 2261 can be in the shape of a plate, a block, a box or other shapes.

[0127] The "Universal Ball Transfer Bull's Eye Bearing" is a special universal ball bearing that combines the features of a universal ball and a bull's eye bearing. This type of bearing typically includes one or more larger diameter spheres (similar to a "bull's eye") placed in a groove or bracket, allowing the object to achieve full rotational and translational motion at the contact point. In specific applications, the Universal Ball Transfer Bull's Eye Bearing 2262 can carry loads from different directions and can flexibly adjust the angle of the load-bearing surface. Therefore, it is very useful in situations requiring high flexibility and heavy load capacity, such as conveying systems, workbench platform supports, material handling equipment, and any mechanical structure that requires free rolling and multi-directional rotation. The design features of the Universal Ball Transfer Bull's Eye Bearing 2262 help reduce friction, improve efficiency, and increase the service life of equipment.

[0128] The embodiment of the present application provides a specific structure of the limit member 226, which includes a mounting member 2261 and a universal ball bull's eye bearing 2262. The mounting member 2261 is used to mount the universal ball bull's eye bearing 2262. The universal ball bull's eye bearing 2262 can support and position the limit fitting member 13. The friction between the universal ball bull's eye bearing 2262 and the inclined guide surface 131 is relatively small, which enables the transport trolley to slide smoothly above the universal ball bull's eye bearing 2262 until the highest point of the universal ball bull's eye bearing 2262 is tightly in contact with the abutting surface, thereby achieving the purpose of positioning.

[0129] Please refer to Figures 3, 4 and 9. In some embodiments, the number of limit members 226 and the limit matching members 13 are both multiple and arranged in one-to-one correspondence. The vertices of the multiple universal ball bull's eye bearings 2262 are located in the same horizontal plane and are not completely on the same straight line. The multiple universal ball bull's eye bearings 2262 jointly support the loading trolley 10.

[0130] The number of the limiting members 226 is multiple and the multiple limiting members 226 are arranged at intervals, the number of the multiple limiting fitting members 13 is also multiple and the multiple limiting fitting members 13 are arranged at intervals, and the limiting members 226 and the limiting fitting members 13 are arranged in a one-to-one correspondence, which means that each limiting member 226 is used to position a limiting fitting member 13.

[0131] For example, in this embodiment, the number of the limiting members 226 and the number of the limiting matching members 13 are both four, and the four universal ball bull's eye bearings 2262 jointly support the loading trolley 10 .

[0132] It can be understood that the number of the limiting members 226 can also be three, five, six, etc., and correspondingly, the number of the limiting matching members 13 can also be three, five, six, etc.

[0133] Among them, the vertices of the multiple universal ball bull's eye bearings 2262 (point P in Figure 9) refer to the highest points of the universal ball bull's eye bearings 2262. The vertices of the multiple universal ball bull's eye bearings 2262 are located in the same horizontal plane, that is, the vertices of the multiple universal ball bull's eye bearings 2262 are set at the same height, that is, the vertices of the multiple universal ball bull's eye bearings 2262 are at the same horizontal height. The vertices of the multiple universal ball bull's eye bearings 2262 are not completely on the same straight line, so that the multiple vertices can jointly define a horizontal plane. In this way, when the multiple limit members 226 respectively clamp the corresponding limit fitting members 13, the horizontality of the loading trolley 10 is corrected, and the loading trolley 10 can remain horizontal, so that the items carried on the loading trolley 10 can be placed horizontally, which is convenient for subsequent grabbing of items or performing other operations.

[0134] The positioning device 20 provided in the embodiment of the present application includes a plurality of limit members 226, and a plurality of limit fitting members 13 are provided on the loading trolley 10. Since the vertices of the plurality of universal ball bull's eye bearings 2262 are located in the same horizontal plane, the plurality of universal ball bull's eye bearings 2262 jointly support the loading trolley 10, and the levelness of the loading trolley 10 is corrected. Even if the ground at the preset position is uneven, the loading trolley 10 can still maintain the levelness. The above-mentioned trolley positioning device 100 not only uses the plurality of limit members 226 to accurately position the loading trolley 10, but also can keep the loading trolley 10 level, thereby realizing the function of level correction.

[0135] In other embodiments, the structure of the limit member 226 is not limited thereto. For example, the limit member 226 may also include a wedge-shaped surface, which is parallel to the inclined guide surface 131. When the highest point of the wedge-shaped surface abuts against the holding surface 132, the limit member 226 can also limit the loading trolley 10 from continuing to move.

[0136] In some embodiments, the number of the limiting members 226 and the limiting fitting members 13 are both four, and two limiting members 226 are respectively provided on both sides of the guide structure along the second direction Y, and the two limiting members 226 on each side are arranged at intervals along the first direction X; the loading trolley 10 is respectively provided with two limiting fitting members 13 on both sides along the second direction Y, and the two limiting fitting members 13 on each side are arranged at intervals along the first direction X.

[0137] In this way, the four limiting members 226 cooperate with the four limiting matching members 13 to simultaneously limit the loading trolley 10 along the first direction X and the second direction Y, and the vertices of the universal ball bull's eye bearings 2262 in the four limiting members 226 are in the same horizontal plane, which can perform horizontal correction on the loading trolley 10.

[0138] As shown in FIG. 9 , in some embodiments, the plurality of limiting members 226 further include a gasket 2263 , which is detachably disposed between the mounting member 2261 and the universal ball bull's eye bearing 2262 . The gasket 2263 is used to increase the height of the universal ball bull's eye bearing 2262 .

[0139] In the limiting member 226 , there can be one or more gaskets 2263 , which can be flexible gaskets 2263 or hard gaskets 2263 . The universal ball bull's eye bearing 2262 and the gasket 2263 are detachably connected to the mounting member 2261 to facilitate the installation of the gasket 2263 .

[0140] Since the ground at the preset position that the loading trolley 10 is to reach may be uneven, this will cause the four corners of the loading trolley 10 to be unbalanced, affecting the subsequent manipulator's grasping of items on the loading trolley 10, and even causing the items to fall and be damaged. In the solution provided in the embodiment of the present application, before the loading trolley 10 arrives, the multiple limiters 226 are pre-calibrated for leveling, and gaskets 2263 are set in several limiters 226 so that the vertices of the multiple universal ball bull's eye bearings 2262 are aligned and in the same horizontal plane. In this way, when the loading trolley 10 is positioned by the multiple universal ball bull's eye bearings 2262, the loading trolley 10 can remain level, avoiding the problem that the loading trolley 10 placement platform is uneven in front, back, left, and right, causing items to collide or fall, or causing the manipulator to be unable to accurately grasp items.

[0141] Please refer to Figure 8. In some embodiments, the side of the limiting fitting 13 facing the limiting member further has a limiting surface 133, the holding surface 132 and the inclined guide surface 131 are arranged on the same side of the limiting surface 133 (on the side along the second direction Y), the second direction Y intersects with the first direction X, and the inclined guide surface 131 is recessed relative to the limiting surface 133.

[0142] The first direction X can be the length of the loading cart 10, and the second direction Y can be the width of the loading cart 10. The inclined guide surface 131 is recessed relative to the limiting surface 133, meaning that the inclined guide surface 131 is recessed toward the top of the loading cart 10, and the limiting surface 133 is lower than the height of the inclined guide surface 131. This creates a groove in the limiting member 13. When the loading cart 10 moves on the limiting member 226, the universal ball bull's eye bearing 2262 can slide relative to the inclined guide surface 131, preventing it from deviating, further improving the accuracy of the movement of the loading cart 10.

[0143] Referring to Figures 1 to 9, some embodiments of the present application provide a trolley positioning device 100, comprising a loading trolley 10 and a positioning device 20. The positioning device 20 comprises a guide structure 21 and a positioning structure 22. The positioning structure 22 comprises a positioning bracket 221 and a precision positioning member 222 disposed on the positioning bracket 221. The loading trolley 10 is provided with a positioning fitting 15, and the precision positioning member 222 is used to engage with the positioning fitting 15. The positioning structure 22 also comprises a positioning drive member 223 disposed on the positioning bracket 221 and a push member 224 connected to the positioning drive member 223. The positioning drive member 223 is used to drive the push member 224 to move, so that the push member 224 applies force to the loading trolley 10, thereby fixing the loading trolley 10 to the positioning bracket 221.

[0144] During use, the guide fitting 14 of the loading trolley 10 enters the guide gap 212 of the guide structure 21, and the guide structure 21 performs rough positioning on the loading trolley 10; when the loading trolley 10 is in place, if there is a deviation in the position of the loading trolley 10, the fine positioning piece 222 can correct the position of the loading trolley 10 until the positioning fitting 15 and the fine positioning piece 222 are engaged with each other to achieve fine positioning; then, the positioning drive piece 223 drives the ejection piece 224 to move, fixing the loading trolley 10 to the positioning bracket 221.

[0145] In the aforementioned trolley positioning device 100, the guide structure 21 guides the loading trolley 10 for rough positioning; the fine positioning member 222 engages with the positioning mating member 15 on the loading trolley 10 for fine positioning; and the positioning drive member 223 and the ejector member 224 hold the loading trolley 10 tightly for parallel positioning. Therefore, the positioning device 20 can accurately position the loading trolley 10.

[0146] The positioning device 20 also includes a limit member 226. A limit fitting member 13 is provided at the bottom of the loading trolley 10. The limit fitting member 13 is provided with an inclined guide surface 131 and a clamping surface 132 on the side facing the limit member 226. The height of the inclined guide surface 131 gradually decreases from the end away from the clamping surface 132 toward the clamping surface 132, and the height of the clamping surface 132 is lower than the height of the inclined guide surface 131. The loading trolley 10 can move over the limit member 226 until the limit member 226 abuts against the clamping surface 132. The limit member 226 includes a mounting member 2261 and a universal ball bull's eye bearing 2262 provided on the mounting member 2261. There are multiple limit members 226 and limit fitting members 13. The vertices (point P) of the multiple universal ball bull's eye bearings 2262 are located in the same horizontal plane. The multiple universal ball bull's eye bearings 2262 jointly support the loading trolley 10. The loading trolley 10 is provided with a positioning fitting 15 . When the loading trolley 10 is attached to the positioning bracket 221 , the positioning fitting 15 and the fine positioning fitting 222 are locked together along the first direction X.

[0147] The trolley positioning device 100 also includes a limiter 226 that accurately positions the loading trolley 10. Multiple limiters 226 collectively adjust the levelness of the loading trolley 10, ensuring that the loading trolley 10 remains level and that items carried on the loading trolley 10 are positioned horizontally, facilitating subsequent retrieval or other operations. The trolley positioning device 100 combines positioning and leveling functions, improving both the positioning and leveling accuracy of the loading trolley 10.

[0148] Referring to Figures 1 to 9, a loading trolley 10 includes a body 11 and a plurality of wheels 12. A handrail 111 is provided on the top of the body 11, and a position-limiting fitting 13 and a positioning fitting 15 are provided on the bottom of the body 11. Optionally, a fixing frame 112 is provided on the bottom of the body 11, and both the position-limiting fitting 13 and the positioning fitting 15 are mounted on the fixing frame 112. This provides a simple structure for the loading trolley 10 and facilitates assembly.

[0149] An embodiment of the second aspect of the present application provides a battery manufacturing device, including the trolley positioning device 100 provided in the first aspect.

[0150] The loading trolley 10 in the trolley positioning device 100 can be used to load battery modules, such as loading NG battery modules.

[0151] The battery manufacturing equipment also includes a manipulator, which is located on one side of the positioning mechanism and is used to grasp the battery modules on the loading cart 10. Because the cart positioning device 100 can accurately position the loading cart 10, the manipulator can accurately grasp the battery modules, eliminating the problem of misplaced grasping and placing caused by inaccurate positioning of the loading cart 10, and avoiding the safety hazards caused by collision and damage to the battery modules.

[0152] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the various embodiments of the present application, and should all be included in the scope of protection of the present application.
