Description

Technical Field

[0001] This invention relates to battery production equipment, specifically a fixture unlocking device and unlocking method. Background Technology

[0002] In the lithium battery production process, to improve the automation rate, it is necessary to fix and lock the cell modules using jigs, and then transport the cell modules to various workstations via conveyor lines.

[0003] After the battery cell module operation is completed, it is usually unlocked and removed from the fixture manually. This unlocking method is inefficient and may damage the battery cell module. In addition, traditional battery cell module fixtures have a complex structure and are cumbersome to unlock. Summary of the Invention

[0004] This invention addresses the problem of low unlocking efficiency of existing battery cell module fixtures by providing a highly efficient fixture unlocking device and method.

[0005] In a first aspect, the present invention provides a jig unlocking device for separating a jig carrying a battery cell module from the battery cell module it carries. The jig includes a guide rail, a first limiting member, a second limiting member, and a positioning member. The first limiting member and the second limiting member are respectively used to limit a first end and a second end of the battery cell module carried. The first limiting member is slidably fitted on the guide rail, and the positioning member is used to position the first limiting member on the guide rail. The jig unlocking device includes an unlocking drive part, a pushing part, and an unlocking part; wherein:

[0006] The driving end of the unlocking drive unit is connected to the pushing part in a transmission connection. The unlocking drive unit drives the pushing part to pass through the hollow structure of the first limiting member and push it to the first end of the battery cell module, so that the battery cell module moves toward the second limiting member and the first limiting member separates from the first end of the battery cell module.

[0007] The unlocking part is configured to disengage the positioning member from the first limiting member and drive the disengaged first limiting member away from the battery cell module.

[0008] The first limiting member of the fixture is separated from the cell module by the pushing part, and the positioning member of the fixture is disengaged from the first limiting member by the unlocking part, thereby realizing the separation of the cell module from the fixture and achieving efficient automatic unlocking of the fixture.

[0009] Optionally, the pushing part includes a movable plate, a connecting plate, and a pushing block. The pushing block is mounted on the connecting plate, the connecting plate is mounted on the movable plate, and the movable plate is mounted on the driving end of the unlocking drive part. The unlocking drive part is configured to drive the pushing block closer to or further away from the first limiting member of the fixture.

[0010] By unlocking the drive unit, the push block is driven to push the first limit member of the fixture, so that the positioning member of the fixture is not subjected to force between it and the guide rail, thus making it easier to pull the positioning member out of the guide rail.

[0011] Optionally, the unlocking drive unit is mounted on the first mounting plate, and a first guide mechanism is installed between the movable plate and the first mounting plate; the first guide mechanism is configured to move the movable plate along the first guide mechanism.

[0012] The first guide mechanism guides the movement of the movable plate, ensuring smooth movement and allowing the pushing part to accurately abut against the first limiting member.

[0013] Optionally, the unlocking part includes a positioning and fixing mechanism and a positioning component disengagement mechanism;

[0014] The positioning and fixing mechanism includes a first lifting component and a pull block. The first lifting component is fixed on the movable plate, and the pull block is installed on the movable end of the first lifting component. The first lifting component is used to drive the pull block to descend so that the pull block presses on the first limiting component.

[0015] The positioning component disengagement mechanism includes a second lifting component and a fork. The second lifting component is installed at the movable end of the first lifting component, and the fork is installed at the movable end of the second lifting component. The second lifting component is used to drive the fork down so that the fork is lower than the upper end of the positioning component, and to drive the fork up to disengage the positioning component.

[0016] The unlocking unit uses a positioning and fixing mechanism to press the pull block onto the first limit member. The positioning member release mechanism then drives the pull fork to rise and release the positioning member, thereby unlocking the fixture.

[0017] Optionally, the first lifting component is mounted on the second mounting plate, the second mounting plate is mounted on the movable plate, the second lifting component is mounted on the third mounting plate, the third mounting plate is mounted on the movable end of the first lifting component, and the pull block is mounted on the third mounting plate.

[0018] A second guide mechanism is installed between the third mounting plate and the second mounting plate; the second guide mechanism is configured to cause the third mounting plate to move up and down along the second guide mechanism.

[0019] The second guide mechanism guides the lifting and lowering of the third mounting plate, ensuring that the pull block can be lifted and lowered smoothly.

[0020] Optionally, a third guide mechanism is installed between the fork and the third mounting plate; the third guide mechanism is configured to cause the fork to move up and down along the third guide mechanism.

[0021] The lifting fork is guided by a third guide mechanism, which ensures that the lifting fork can be raised and lowered smoothly.

[0022] Optionally, the fixture unlocking device also includes a lifting part, which is mounted on the frame. The unlocking drive part, the pushing part, and the unlocking part are all mounted on the movable end of the lifting part. The lifting part is used to drive the unlocking drive part, the pushing part, and the unlocking part to move up and down.

[0023] The lifting mechanism drives the entire unit to rise and fall, preventing interference between the battery cell module and the unlocking device in the height direction, and facilitating the operation of the battery cell module in subsequent processes.

[0024] Optionally, the fixture unlocking device also includes a translation section, on which the frame is mounted, and the translation section is used to translate the frame.

[0025] The lifting mechanism drives the entire unit to move horizontally, which prevents interference between the battery cell module and the unlocking device in the horizontal direction and facilitates the operation of the battery cell module in subsequent processes.

[0026] Optionally, a locking mechanism is installed on the translation section, which is configured to lock the frame onto the translation section.

[0027] The locking mechanism locks the horizontal position of the entire machine, preventing it from shaking during operation and facilitating operation.

[0028] Optionally, the fixture unlocking device also includes a sensing unit mounted on the side of the fixture. The sensing unit is used to sense the specification information of the battery cell module inside the fixture, and the translation unit determines the translation distance based on the information.

[0029] The sensor unit senses the specifications of the battery cell module within the fixture, and the translation unit determines the translation distance of the entire machine based on this specifications, thereby positioning the entire machine in a suitable working position.

[0030] Secondly, the present invention provides a jig unlocking method, employing a jig unlocking device, the jig unlocking method comprising:

[0031] The control pusher pushes against the first end of the battery cell module, causing the battery cell module to move toward the second limiting member, and the first limiting member separates from the first end of the battery cell module;

[0032] The control unlocking unit disengages the positioning component from the first limiting component;

[0033] The control unlocking unit moves away from the first limiting member, which disengages from the battery cell module.

[0034] The battery cell module is separated from the fixture by a fixture unlocking device, achieving efficient automatic fixture unlocking.

[0035] Thirdly, the present invention provides a jig unlocking method, employing a jig unlocking device, the jig unlocking method comprising:

[0036] The second lifting component drives the fork to descend, making the fork lower than the upper end of the positioning component;

[0037] The unlocking drive unit drives the push block to push the first end of the battery cell module carried by the fixture, causing the battery cell module to move toward the second limiting member. At the same time, the unlocking drive unit drives the shift fork to descend so that the shift fork is lower than the upper end of the positioning member.

[0038] The first lifting component drives the pull block to descend, causing the pull block to press against the first limiting component;

[0039] The second lifting component drives the fork to rise and pull the positioning component out of the guide rail, thus separating the positioning component from the first limiting component.

[0040] The unlocking drive unit drives the pull block to move away from the battery cell module, which in turn drives the first limiting member away from the battery cell module, causing the first limiting member to separate from the battery cell module.

[0041] The jig unlocking device uses a pull block in the jig to press against the first limit member, and a fork to pull out the positioning member, thereby achieving efficient automatic jig unlocking. Attached Figure Description

[0069] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0070] like Figures 1-4 As shown, the present invention provides a jig unlocking device 1 for separating the jig 10 carrying the battery cell module from the battery cell module it carries.

[0071] like Figures 5-9 As shown, the fixture 10 includes a guide rail 131, a first limiting member 132, a second limiting member 133, and a positioning member 134. The first limiting member 132 and the second limiting member 133 are used to limit the first end and the second end of the battery cell module they carry, respectively. The first limiting member 132 is slidably fitted on the guide rail 131, and the positioning member 134 is used to position the first limiting member 132 on the guide rail 131.

[0072] Figures 5-7 The diagram shows one alternative embodiment of the fixture 10. Figure 8 , Figure 9 The diagram shows another alternative embodiment of the fixture 10. The difference between the two lies in the structure of the lower steel belt limiting block 14.

[0073] like Figures 5-7 and Figure 8 , Figure 9 As shown, both embodiments of the fixture 10 include a base plate 11, a support frame 12, a first limiting component 13, and a lower steel belt limiting block 14.

[0074] The base plate 11 is generally rectangular, and guide wheels 15 can be installed at the four corners of the rectangle. The guide wheels 15 play a guiding role when the fixture 10 moves.

[0075] The first limiting component 13 is mounted on the base plate 11 and is used to fix the battery cell module. The first limiting component 13 includes a guide rail 131, a first limiting member 132, a second limiting member 133, and a positioning member 134.

[0076] The guide rail 131 is installed in the middle of the upper surface of the base plate 11 and extends along the length of the base plate 11. A guide groove 161 is formed on the upper surface of the guide rail 131 along the length direction to serve as a guide. A plurality of positioning holes 162 are formed on the bottom plane of the guide groove 161. The positioning holes 162 are used to cooperate with the pins in the positioning member 134 to serve as positioning.

[0077] The first limiting member 132 and the second limiting member 133 are located on both sides of the support frame 12 and are slidably engaged with the guide rail 131. Spaces for accommodating the lower steel strip are provided between the first limiting member 132 and the support frame 12, and between the second limiting member 133 and the support frame 12. The first limiting member 132 and the second limiting member 133 are configured to abut against the battery cell module from both sides of the support frame 12.

[0078] The first limiting member 132 and the second limiting member 133 are respectively positioned on the guide rail 131 by two positioning members 134. The two positioning members 134 are respectively installed on the first limiting member 132 and the second limiting member 133.

[0079] The support frame 12 is fixed at the center above the guide rail 131, and is used to support the battery cell module. Optionally, the support frame 12 consists of a flat plate and two vertical plates. The flat plate is fixed on the guide rail 131, and the two vertical plates are fixed parallel and spaced above the flat plate, with the extending direction of the vertical plates parallel to the extending direction of the guide rail 131. The two vertical plates are used to suspend the battery cell module above the guide rail 131.

[0080] The first limiting member 132 and the second limiting member 133 are respectively equipped with a lower steel strip limiting block 14. The lower steel strip limiting block 14 is configured to hold the lower steel strip on the battery cell module after the lower steel strip is sleeved on the shaped battery cell module.

[0081] The battery cell module is fixed on the support frame 12 by the first limiting component 13, and the lower steel strip is held on the battery cell module by the lower steel strip limiting block 14, which prepares for the subsequent shaping of the battery cell module.

[0082] The first limiting member 132 and the second limiting member 133 can adopt any structure in the prior art. Optionally, a fixed limiting block 135 is installed on one of the first limiting member 132 and the second limiting member 133, and an elastic limiting block 136 is installed on the other of the first limiting member 132 and the second limiting member 133. The elastic limiting block 136 is generally composed of a spring and a limiting block, with the limiting block abutting against the spring, and the spring pressing the limiting block against the battery cell module. In addition, the first limiting member 132 and the second limiting member 133 are also provided with space to avoid the pressing block 321 of the pressing mechanism 32, so that the pressing block 321 can press against the battery cell module.

[0083] The limiting block in the first limiting component 13 combines a fixed limiting block 135 with an elastic limiting block 136. The elastic limiting block 136 has a certain amount of compression, which can allow the cell module to have a certain limit of error, thus improving the adaptability of the fixture 10.

[0084] The lower steel strip limiting block 14 is set at the corresponding position of the lower steel strip on the battery cell module. After the lower steel strip is manually fitted, the spring force presses the lower steel strip to prevent it from slipping off. Optionally, the lower steel strip limiting block 14 can be a hemispherical pressure block 141 or a trapezoidal pressure block 142.

[0085] The lower steel strip limiting block 14 can be selected in different types according to different production site conditions: the hemispherical pressure block 141 will not jam the lower steel strip; the inclined surface of the trapezoidal pressure block 142 can guide the lower steel strip, making it easier for the lower steel strip to pass through from bottom to top, and the flat surface of the trapezoidal pressure block 142 can support the lower steel strip, making it difficult for the lower steel strip to slip down.

[0086] Figures 5-7 The jig 10 shown uses a hemispherical pressure block 141. The hemispherical pressure block 141 is mounted on the first limiting member 132 and the second limiting member 133 by springs, and the spring force presses the hemispherical pressure block 141 onto the lower steel strip.

[0087] Figure 8 , Figure 9 The fixture 10 shown uses a trapezoidal pressure block 142. The trapezoidal pressure block 142 is mounted on a spring sheet, and the spring sheet's elastic force presses the trapezoidal pressure block 142 onto the lower steel strip.

[0088] See also Figures 1-4 The fixture unlocking device 1 mainly includes an unlocking drive unit 20, a pushing unit 30, and an unlocking unit 40.

[0089] The driving end of the unlocking drive unit 20 is connected to the pushing part 30. The unlocking drive unit 20 drives the pushing part 30 through the hollow structure of the first limiting member 132 and pushes it to the first end of the battery cell module, so that the battery cell module moves toward the second limiting member 133 and the first limiting member 132 separates from the first end of the battery cell module. The unlocking part 40 is configured to disengage the positioning member 134 from the first limiting member 132 and drive the disengaged first limiting member 132 away from the battery cell module.

[0090] The first limiting member 132 of the fixture 10 is separated from the battery cell module by the pushing part 30, and the positioning member 134 of the fixture 10 is disengaged from the first limiting member 132 by the unlocking part 40, thereby realizing the separation of the battery cell module from the fixture 10 and achieving efficient automatic unlocking of the fixture 10.

[0091] Optionally, the unlocking drive unit 20 may be a linear motor, a pneumatic cylinder, or a hydraulic cylinder.

[0092] like Figures 10-14As shown, in one optional embodiment, the pushing part 30 includes a movable plate 31, a connecting plate 32, and a pushing block 33. The pushing block 33 is mounted on the connecting plate 32, the connecting plate 32 is mounted on the movable plate 31, and the movable plate 31 is mounted on the driving end of the unlocking drive part 20. The unlocking drive part 20 is configured to drive the pushing block 33 to move closer to or further away from the first limiting member 132 of the fixture 10.

[0093] By unlocking the drive unit 20, the push block 33 pushes against the first limiting member 132 of the fixture 10, so that the positioning member 134 of the fixture 10 is not subjected to force with the guide rail 131, thereby making it easier to pull the positioning member 134 out of the guide rail 131.

[0094] In this embodiment, optionally, the unlocking drive unit 20 is mounted on the first mounting plate 21, and a first guide mechanism 22 is installed between the moving plate 31 and the first mounting plate 21; the first guide mechanism 22 is configured to move the moving plate 31 along the first guide mechanism 22. Optionally, the first guide mechanism 22 employs a sliding block and a sliding rail that cooperate with each other.

[0095] The first guide mechanism 22 guides the movement of the movable plate 31, ensuring smooth movement and allowing the pushing part 30 to accurately abut against the first limiting member 132.

[0096] In one embodiment, the push block 33 is composed of two parallel, spaced-apart "7"-shaped flat plates. The "7"-shaped flat plates can be pushed against the first limiting member 132 and match the first limiting member 132.

[0097] like Figure 10 , Figure 11 and Figures 15-18 As shown, as an optional implementation, the unlocking part 40 includes a positioning and fixing mechanism 41 and a positioning member disengagement mechanism 42.

[0098] The positioning and fixing mechanism 41 includes a first lifting member 411 and a pull block 412. The first lifting member 411 is fixed on the moving plate 31, and the pull block 412 is installed on the movable end of the first lifting member 411. The first lifting member 411 is used to drive the pull block 412 down so that the pull block 412 presses on the first limiting member 132.

[0099] The positioning member disengagement mechanism 42 includes a second lifting member 421 and a fork 422. The second lifting member 421 is installed at the movable end of the first lifting member 411, and the fork 422 is installed at the movable end of the second lifting member 421. The second lifting member 421 is used to drive the fork 422 down so that the fork 422 is lower than the upper end of the positioning member 134, and to drive the fork 422 up to disengage the positioning member 134.

[0100] The unlocking unit 40 uses the positioning and fixing mechanism 41 to press the pull block 412 onto the first limiting member 132, and the positioning member release mechanism 42 drives the pull fork 422 to rise and release the positioning member 134, thereby unlocking the fixture 10.

[0101] In this embodiment, the first lifting member 411 and the second lifting member 421 can be cylinders or hydraulic cylinders; the pull block 412 and the pull fork 422 have U-shaped grooves, which can hold the positioning member 134 in the U-shaped grooves.

[0102] In one embodiment, optionally, a first lifting member 411 is mounted on a second mounting plate 413, the second mounting plate 413 is mounted on a movable plate 31, a second lifting member 421 is mounted on a third mounting plate 423, the third mounting plate 423 is mounted on the movable end of the first lifting member 411, and a pull block 412 is mounted on the third mounting plate 423. A second guide mechanism 414 is installed between the third mounting plate 423 and the second mounting plate 413; the second guide mechanism 414 is configured to cause the third mounting plate 423 to move up and down along the second guide mechanism 414.

[0103] The second guide mechanism 414 guides the lifting and lowering of the third mounting plate 423, ensuring that the pull block 412 can be lifted and lowered smoothly.

[0104] Optionally, a third guide mechanism 424 is installed between the fork 422 and the third mounting plate 423; the third guide mechanism 424 is configured to cause the fork 422 to move up and down along the third guide mechanism 424.

[0105] The lifting and lowering of the fork 422 is guided by the third guide mechanism 424, which ensures that the fork 422 can be lifted and lowered smoothly.

[0106] Optionally, the second guide mechanism 414 and the third guide mechanism 424 respectively adopt a slider and a slide rail that cooperate with each other.

[0107] like Figures 1-4 As shown, in an optional embodiment, the fixture unlocking device 1 further includes a lifting part 50, which is mounted on the frame 51. The unlocking drive part 20, the pushing part 30, and the unlocking part 40 are all mounted on the movable end of the lifting part 50. The lifting part 50 is used to drive the unlocking drive part 20, the pushing part 30, and the unlocking part 40 to move up and down. Specifically, the unlocking drive part 20 is mounted on the frame 51 via a first mounting plate 21. Optionally, the lifting part 50 can be a pneumatic cylinder or a hydraulic cylinder.

[0108] The lifting unit 50 drives the overall lifting, which can prevent interference between the battery cell module and the unlocking device in the height direction, and facilitate the operation of the battery cell module in subsequent processes.

[0109] In this embodiment, optionally, the fixture unlocking device 1 further includes a translation part 60, on which the frame 51 is mounted, and the translation part 60 is used to translate the frame 51.

[0110] The lifting unit 50 drives the entire unit to move horizontally, which can prevent interference between the battery cell module and the unlocking device in the horizontal direction and facilitate the operation of the battery cell module in subsequent processes.

[0111] In one embodiment, optionally, a locking mechanism 61 is mounted on the translation section 60, the locking mechanism 61 being configured to lock the frame 51 onto the translation section 60.

[0112] The locking mechanism 61 locks the horizontal position of the entire machine, preventing it from shaking during operation and facilitating operation.

[0113] As an optional implementation, the jig unlocking device 1 also includes a sensing unit 70, which is mounted on the side of the jig 10. The sensing unit 70 is used to sense the specification information of the battery cell module inside the jig 10, and the translation unit 60 determines the translation distance based on the information.

[0114] The sensing unit 70 senses the specification information of the battery cell module within the fixture 10, and the translation unit 60 determines the translation distance of the entire machine based on this specification information, thereby positioning the entire machine in a suitable working position. Optionally, the sensing unit 70 may include a proximity switch or a diffuse reflection photoelectric sensor.

[0115] like Figures 1-4 and Figure 10 , Figure 11 As shown, the operation flow of the jig unlocking device 1 is as follows:

[0116] 1. The lifting unit 50 drives the entire structure to descend; at this time, the first lifting component 411 is in the retracted state, and the second lifting component 421 is in the extended state;

[0117] 2. The unlocking drive unit 20 drives the moving plate 31 forward, and the pull fork 422 and the pull block 412 extend from the head end of the pin of the positioning member 134 and the spring block; at this time, the pushing part 30 pushes the battery cell module slightly towards the second limiting member 133, so that the first limiting member 132 is not under force, making it easier to pull out the pin.

[0118] 3. The first lifting component 411 extends, causing the pull block 412 to press down; the second lifting component 421 retracts, causing the fork 422 to move upward, causing the pin of the positioning component 134 to move upward, and pulling out the pin.

[0119] 4. The translation part 60 drives the whole to move away from the first limiting member 132, so that the pull block 412 pulls the stop block of the positioning member 134, thereby driving the first limiting member 132 to move away from the first limiting member 132 together, thereby releasing the battery cell module.

[0120] 5. After the battery cell module is unlocked, the subsequent unloading robot will move the battery cell module away from fixture 10.

[0121] like Figures 1-4 As shown, the present invention provides a jig unlocking method, employing a jig unlocking device 1, the jig unlocking method comprising:

[0122] The control pusher 30 pushes against the first end of the battery cell module, causing the battery cell module to move toward the second limiting member 133, and the first limiting member 132 separates from the first end of the battery cell module;

[0123] The control unlocking unit 40 disengages the positioning member 134 from the first limiting member 132;

[0124] The control unlocking unit 40 moves the first limiting member 132 away from the battery cell module.

[0125] The battery cell module is separated from the fixture 10 by the fixture unlocking device 1, which realizes efficient automatic unlocking of the fixture 10.

[0126] like Figure 10 , Figure 11 As shown, the present invention also provides another method for unlocking a jig, using a jig unlocking device 1, the method comprising:

[0127] The second lifting component 421 drives the fork 422 to descend, so that the fork 422 is lower than the upper end of the positioning component 134;

[0128] The unlocking drive unit 20 drives the push block 33 to push the first end of the battery cell module carried by the fixture 10, so that the battery cell module moves toward the second limiting member 133. At the same time, the unlocking drive unit 20 drives the pull fork 422 to descend so that the pull fork 422 is lower than the upper end of the positioning member 134.

[0129] The first lifting component 411 drives the pull block 412 to descend, causing the pull block 412 to press against the first limiting component 132;

[0130] The second lifting component 421 drives the fork 422 to rise and pull the positioning component 134 out of the guide rail 131, so that the positioning component 134 is separated from the first limiting component 132.
