Description

Technical Field

[0001] This invention relates to the field of battery module installation technology, and in particular to a manual clamping multi-row module floating shaping and pressure-holding tray, placement structure and method. Background Technology

[0002] In the mass production of new energy power batteries, after the front-end process, the cell module is prone to dimensional deviations in the length and width directions and poor consistency of the width of a single row of modules, which makes it impossible to put it into the module tray smoothly, thus affecting the accurate implementation of subsequent processes such as pole positioning, side plate welding, and pole electrode welding.

[0003] A patent search revealed that existing module trays mostly involve simple length-direction extrusion, requiring automated equipment or mechanisms for extrusion followed by locking with a T-screw or guide rail. Existing structures can only achieve simple length-direction extrusion and are unsuitable for small-scale pilot production or low-automation production lines, thus hindering equipment investment and operational efficiency. They are not suitable for small-scale pilot production or low-automation production lines.

[0004] In the mass production of new energy power batteries, after the front-end process, the cell module is prone to dimensional deviations in the length and width directions and poor consistency of the width of a single row of modules, which makes it impossible to put it into the module tray smoothly, thus affecting the accurate implementation of subsequent processes such as pole positioning, side plate welding, and pole electrode welding.

[0005] Existing patented modules also lack side or width dimensions, making it difficult to extrude and shape multiple modules in a single operation, resulting in a lack of shaping efficiency and precision consistency. For example, in the prior art CN202211654981.2, a battery module assembly tray can only limit movement in the width direction, not extrude in that direction. Furthermore, it cannot make fine adjustments between adjacent cell modules in the width direction to compensate for width deviations, making it impossible to smoothly place the module into the tray.

[0006] To address these issues, this invention proposes a manual clamping mechanism, placement structure, and method for floating shaping and pressure-holding trays of multiple modules. Summary of the Invention

[0007] To overcome the above deficiencies, the present invention provides a manual clamping multi-row module floating shaping and pressure-holding tray, placement structure and method, which solves the technical problems in the prior art of lacking length and width to compress the battery cell modules and being unable to compensate for the installation of multiple battery cell modules.

[0024] In a further technical solution, the partition floating mechanism also includes a left fixed baffle and a right fixed baffle, and the module housing is provided with multiple sets and arranged in parallel; the left fixed baffle and the right fixed baffle are located on opposite sides of two sets of module housings on the two sides of the multiple sets of module housings;

[0025] The left and right fixed baffles are bent relative to each other and are jointly supported on the side of the corresponding module housing;

[0026] The positioning structure includes a positioning ring, and the bottom of the base plate frame has a bottom hole, in which the positioning ring is detachably installed. A positioning pin hole is provided in the middle of the positioning ring.

[0027] Multiple sets of lifting rings are also installed on the bottom plate of the pallet.

[0028] A placement structure for manually clamping multi-row module floating shaping and pressure-holding trays includes a frame, with recessed steps on both sides of the frame and a bearing plane in the middle.

[0029] The base frame is rectangular in shape, with guide rollers installed at its four corners. The guide rollers are constrained to the inner sides of two sets of steps. The base frame is also equipped with stops and anti-pinch blocks on its sides. Both stops and anti-pinch blocks are placed on the steps and are used to support the base frame on the bearing plane. The anti-pinch blocks are located along the length of the base frame and are longer than the length of the stops. The length of the anti-pinch blocks is greater than the width of the steps.

[0030] In a further technical solution, both the intermediate fixed partition and the floating partition have a two-lobed structure and an internal receiving cavity, in which an elastic airbag is installed.

[0031] A compression hole is provided in the middle of the receiving cavity, and an elastic plug is installed in the compression hole. One end of the elastic plug is inserted into the compression hole and connected to the elastic airbag.

[0032] A pressure sensor is installed at the top of the receiving cavity, with the detection end facing downwards; the top of the elastic airbag moves to abut against the detection end of the pressure sensor;

[0033] The bottom of the elastic airbag is provided with a rising plate and a rising spring. The bottom of the rising spring is fixedly connected to the bottom of the receiving cavity, and the top is fixedly connected to the rising plate. The rising plate is connected to the bottom of the elastic airbag.

[0034] The elastic plug is mounted on a support plate, which is movably connected to the side of the module housing; the extrusion hole is a stepped hole, and a lateral spring is installed between the elastic plug and the stepped surface of the extrusion hole.

[0035] In a further technical solution, the positioning structure also includes a bottom plate, which includes an arc-shaped portion and a guide portion. The arc-shaped portion is concentric with the positioning ring. A connecting bearing is installed between the arc-shaped portion and the positioning ring. The arc-shaped portion has an opening.

[0036] The guide section is connected to the end of the arc-shaped opening; the two sets of guide sections are tapered and a positioning plate is provided between them, and the positioning plate is detachably connected to the base frame;

[0037] The positioning rings are arranged in four sets in a rectangular pattern. Positioning components are installed at the bottom of the base plate frame. The positioning components are located between two adjacent sets of base plates and their height is not greater than the height of the base plate.

[0038] The positioning component includes a positioning cylinder, a connecting column installed inside the positioning cylinder, the connecting column being inserted into the arc-shaped part and an abutment plate being installed inside the arc-shaped part, the abutment plate being used to abut against the tooling inserted into the positioning pin hole;

[0039] Both sets of connecting columns are fitted with limit springs inside the positioning cylinder, and the ends of the connecting columns away from the abutment plate are equipped with flexible shafts. The middle of the flexible shafts is constrained by a sliding group and slides at the bottom of the base plate frame.

[0040] The shaping method for manually clamping multi-row module floating shaping and pressure-holding trays also includes the following steps:

[0041] Step 1: Manually place multiple rows of battery cell modules to be shaped into the module housing in sequence, with the initial width deviation of each row of modules 3 within ±3mm;

[0042] Step 2: First, operate the entire width direction by pushing through the output end of the quick clamp to push the floating partition and the middle fixed partition to fit against both sides of the cell module, thus completing the width pre-clamping;

[0043] Step 3: Then, use the quick clamps at both ends of the length to push and squeeze from both ends of the module shell length, and simultaneously lock all clamp handles to hold pressure for 10 seconds.

[0044] Step 4: After the pressure holding is completed, release all quick clamps one and two. The length and width dimensions of the four rows of battery cell modules are uniform, and the width tolerance is controlled within ±0.2mm.

[0045] Step 5: After the shaping is completed, the base plate frame is locked to the production line positioning fixture through the positioning pin hole at the bottom, and then directly transferred to the next station to carry out the pole positioning and side plate welding processes, without the need for secondary transfer and repeated positioning.

[0046] The present invention has the following beneficial effects:

[0047] 1. This invention uses a quick clamp to manually perform module clamping, shaping and pressure holding operations. The equipment investment cost is low and the operation threshold is low. It can be adapted to the use scenarios of small-scale trial production and low automation production lines, which greatly reduces the equipment investment for small and medium batch production of battery cell modules. It can also be equipped with additional positioning mechanisms or equipment to complete specific production processes.

[0048] 2. By combining the length forming clamp mechanism and the width clamping forming mechanism with the floating partition structure, the length and width bidirectional extrusion forming of multiple rows of battery cell modules can be completed simultaneously. The floating partition achieves adaptive sliding in the width direction with the help of the waist-shaped hole and the guide post, which can be compatible with the module width dimensional tolerance within ±5mm. This enables the simultaneous forming of multiple rows of modules at one time, effectively improving the efficiency of the forming operation, unifying the dimensional accuracy of each row of modules, improving the consistency of module dimensions, and providing a regular workpiece foundation for subsequent welding processes.

[0049] 3. The bottom of the tray base frame is equipped with positioning pin holes, which can be accurately docked and positioned with production line conveying equipment, positioning fixtures and testing mechanisms. This breaks through the limitation that the existing shaping station can only be used independently by a single machine. It enables the shaping process to work in conjunction with upstream and downstream processes such as electrode positioning, side plate welding and electrode sheet welding, thereby improving the continuity of the entire battery module production line and reducing errors and time losses caused by workpiece transfer and repeated positioning.

[0050] 4. The overall structure is highly integrated and easy to disassemble and maintain. The quick clamps with different clamping force specifications can be replaced according to the different module shaping process requirements, which can be adapted to the shaping and processing needs of various single-row and multi-row battery cell modules. The equipment has a simple structure and controllable manufacturing cost, taking into account both practicality and economy, making up for the application shortcomings of existing module shaping trays, and has a wider range of applications.

[0051] 5. In this invention, elastic plugs are used to laterally compress each battery cell module via a support plate, forming and maintaining the pressure of the battery cell module. Secondly, during compression, the lateral pressure of two sets of quick-clamping clamps compresses the elastic plugs against the position plate located at the top of the elastic airbag, allowing for pressure detection. A remote alarm can also be installed to measure and trigger an alarm, ensuring the pressure does not exceed the limit. Furthermore, the elastic airbag supports the elastic plugs and lateral springs, ensuring that the battery cell module is buffered during compression and does not experience concentrated force, thus preventing wear on the surface of the battery cell module and its casing.

[0052] 6. This invention guides the bottom connecting structure of the carrying tray to be inserted into the positioning pin by setting a guide part, and constrains the rotation of the lower tooling by moving the connecting columns at both ends through the installation of a flexible shaft to pull the connecting plates at both ends. The flexible shaft is quickly reset after being pulled by limit springs at both ends. Attached Figure Description

[0081] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0082] Example 1

[0083] like Figure 1-8 The image shows one embodiment of the present invention, specifically a manually clamping multi-row module floating shaping and pressure-holding tray, comprising:

[0084] The bottom plate 1 of the pallet is flat with notches at the four corners for mounting lifting rings on the surface for overall lifting.

[0085] like Figure 7 As shown, the base frame 10 is installed at the bottom of the tray lower base plate 1 and is detachably connected to the tray lower base plate 1. The base frame is rectangular in shape, and there are connecting rods distributed horizontally and vertically inside, all of which are bolted to the tray lower base plate from the bottom. In this embodiment, the base frame is welded from 8mm thick steel. Four sets of φ8 positioning pin holes are evenly opened on the bottom surface of the base frame. The center distance of the pin holes matches the positioning reference of the standard conveyor tooling of the power battery module production line, and can be directly placed on the production line roller conveyor and positioning fixture to complete locking and positioning.

[0086] like Figure 1 and 2 The battery cell module 3 is installed on the bottom plate 1 of the tray; multiple battery cells are arranged for subsequent connection. The module shell 15 encloses the battery cell module and is used to support and protect the battery cell module 3.

[0087] like Figure 3 As shown, the length shaping mechanism 4 is installed at one end of the battery cell module 3 and located at the end of the battery cell module 3 in the length direction, and is used to constrain the length direction of the battery cell module 3.

[0088] like Figure 4 As shown, the width clamping and shaping mechanism 2 is installed on both sides of the battery cell module 3, and is used to constrain and squeeze multiple sets of battery cell modules 3 along the width direction of the battery cell module 3;

[0089] like Figure 1 and 2 As shown, the partition floating mechanism includes a middle fixed partition 6 and a floating partition 5. The middle fixed partition 6 or the floating partition 5 is installed between adjacent module housings 15. The floating partition 5 has an oblong hole 51 arranged along the width direction, so that the floating partition 5 can be adjusted in position along the width direction of the module housing 15.

[0090] In this embodiment, a single floating partition plate is provided with four elongated slotted holes along its width direction, such as... Figure 8 and 2 As shown, the waist-shaped hole is 12mm long and 6mm wide; the floating partition can slide back and forth along the width direction of the cell module, with a maximum sliding stroke of 5mm on one side and a total of ±5mm on both sides, which can accommodate module width tolerances within the range of ±5mm, and is suitable for multi-row cell modules with width deviations after front-end processing.

[0091] The positioning structure is set at the bottom of the base frame 10.

[0092] A pad is placed at the bottom of the battery cell module, and a 10mm thick polyurethane wear-resistant pad is used. It is laid on the bearing area of ​​the tray bottom plate to avoid scratching and damage to the battery cells; a set of floating partition mechanism is set between the bearing areas of multiple rows of battery cell modules, for a total of 3 sets of floating partitions.

[0093] like Figure 2 As shown, the length shaping mechanism 4, the width clamping and shaping mechanism 2, the partition floating mechanism, and the module shell 15 are all assembled above the bottom plate 1 of the tray.

[0094] An adjustable oblong hole 51 along the width direction of the cell module 3 is formed on the floating partition 5, such as... Figure 5 As shown, a guide post 9 is installed in the waist-shaped hole 51. The guide post constrains the floating partition on the bottom plate 1 of the tray, so that it can move along the length direction of the waist-shaped hole.

[0095] like Figure 3 As shown, the length shaping mechanism 4 includes an end seat 41 and a quick clamp 42. The bottom of the end seat 41 is connected to the bottom plate 1 of the tray, and the top is detachably connected to the quick clamp 42. An end plate 43 is detachably connected to the output end of the quick clamp 42. An elastic plate 44 is provided on the side of the end plate 43 facing the module housing 15 and is used to movably constrain the end of the module housing 15. A slider 45 is installed at the bottom of the end plate 43, and slide rails 46 are provided on both sides of the end seat 41. The slider 45 is adapted to be installed on the slide rails 46.

[0096] Length shaping mechanism: Two manual quick clamps with a clamping force of 150kg are installed at each end of the bottom plate 1 of the tray. The clamp push head is equipped with a nylon buffer pressure block. By operating the clamp handle, the battery cell module can be squeezed inward from both ends of the length at the same time to complete the length shaping and pressure holding. The pressure holding time can be freely controlled by the operator. The single shaping and pressure holding time is set to 10s.

[0097] like Figure 6As shown, a locking plate 47 is installed at the end of the module housing 15 along its length direction. The locking plate 47 is located at the end of the module housing 15 away from the quick clamp 42. The top of the locking plate 47 supports the module housing 15, and the bottom is detachably connected to the tray bottom plate 1.

[0098] like Figure 4 As shown, the width clamping and shaping mechanism 2 includes a side seat 21 and a quick clamp 22. The bottom of the side seat 21 is detachably connected to the bottom plate 1 of the tray, and the top is detachably connected to the quick clamp 22. The output end of the quick clamp 22 is provided with a clamping plate 23, which is fixedly connected to the side plate 24. The side plate 24 is provided with an elastic plate 25 on the side facing the battery cell module 3.

[0099] The second quick clamp has a clamping force of 120kg. The clamp push block presses against the clamping plate, and works in conjunction with the side plate to simultaneously complete the one-time compression of multiple rows of battery cell modules in the width direction. The floating partition slides adaptively with the actual width of each row of modules to ensure that each row of battery cell modules is evenly compressed, realizing the synchronous batch shaping of multiple rows.

[0100] like Figure 2 The partition floating mechanism further includes a left fixed baffle 7 and a right fixed baffle 8, and multiple sets of module housings 15 are arranged in parallel; the left fixed baffle 7 and the right fixed baffle 8 are located on opposite sides of two sets of module housings 15 on the two sides of the multiple sets of module housings 15.

[0101] The left fixed baffle 7 and the right fixed baffle 8 are bent relative to each other and are jointly supported on the side of the corresponding module housing 15;

[0102] The module housing includes a first end module side plate and a second side module side plate. The first module side plate corresponds to the length shaping mechanism and is movably compressed by the first elastic plate. The second module side plate corresponds to the width clamping and shaping mechanism and is movably compressed by the second elastic plate. The first module side plate and the second module side plate are symmetrically arranged to form a housing with an upward opening, which is used to support the battery cell module. The interior is filled with a polyurethane wear-resistant pad.

[0103] like Figure 7 As shown, the positioning structure includes a positioning ring 17. The bottom of the base plate frame 10 has a bottom hole, and the positioning ring 17 is detachably installed in the bottom hole. The positioning ring 17 has a positioning pin hole 14 in the middle.

[0104] Multiple sets of lifting rings 18 are also installed on the bottom plate 1 of the tray.

[0105] After being stacked, the battery cell modules are placed on the bottom plate of the tray. If there is a large deviation in the width direction of the battery cell modules, the floating partition 5 between adjacent battery cell modules can be slightly displaced in the width direction under the guidance of the guide column. The width clamping and shaping machine is operated to push the quick clamp two to squeeze the width of the battery cell modules in the width direction. During the squeezing process, the floating partition can also be slightly displaced. Finally, the battery cell modules between the middle fixed partition and the left fixed baffle are pushed from left to right towards the middle fixed partition under the pushing action of the quick clamp two. The other columns of modules are pushed from right to left towards the middle fixed partition under the push of the width clamping and shaping mechanism on the right side. Finally, the width direction floating shaping and pressure holding are achieved under the action of the clamp. Similarly, after the modules are stacked, the length direction is shaped and pressure held under the clamping action of the quick clamp one.

[0106] The shaping method for manually clamping multi-row module floating shaping and pressure-holding trays also includes the following steps:

[0107] Step 1: Manually place multiple rows of battery cell modules 3 to be shaped into the module housing 15 in sequence, with the initial width deviation of each row of modules 3 within ±3mm;

[0108] Step 2: First, operate the entire width direction by pushing through the output end of the quick clamp 42 to push the floating partition 5 and the middle fixed partition 6 to fit against the two sides of the cell module 3, thus completing the width pre-clamping.

[0109] Step 3: Then, use the quick clamps 22 to push and squeeze the two ends of the module housing 15 from both ends of the length, and simultaneously lock all clamp handles to hold the pressure for 10 seconds.

[0110] Step 4: After the pressure holding is completed, release all the quick clamps 1 42 and quick clamp 2 22. The length and width dimensions of the 4-row battery cell module 3 are uniform, and the width dimension tolerance is controlled within ±0.2mm.

[0111] Step 5: After the shaping is completed, the base plate frame 10 is locked to the production line positioning fixture through the bottom positioning pin hole 14, and directly transferred to the next station to carry out the pole positioning and side plate welding processes, without the need for secondary transfer and repeated positioning.

[0112] This embodiment has no complex components such as T-shaped lead screws, servo guides, and automated drive modules. It relies solely on manual quick clamps to complete all shaping actions. The equipment manufacturing cost is reduced by 65% ​​compared to fully automated shaping equipment. No professional automation maintenance personnel are required for operation. It is suitable for small and medium-sized enterprises to use in small-scale trial production and simple production lines with low automation.

[0113] Furthermore, different clamping force models of quick clamps can be replaced according to the specifications of the battery cell module: for thick, large-capacity battery cell modules, replace with heavy-duty quick clamps with a clamping force of 300kg or more; for small, thin battery cell modules, replace with light-duty quick clamps with a clamping force of 80kg.

[0114] The positioning pin holes at the bottom of the device are aligned with the positioning reference of the production line inspection fixtures and welding fixtures. After the shaping is completed, the pallet is directly transferred with the conveyor line, eliminating the workpiece loading and unloading transfer process. The overall production time of a single batch of multi-column modules is shortened by 18 seconds, eliminating the 0.3 to 0.5 mm positioning error caused by repeated positioning, and significantly improving the continuity of the entire module production line process.

[0115] All embodiments of this invention abandon high-cost automated components such as lead screws, servo guides, and automatic locking mechanisms, and rely on manual quick clamps to achieve clamping and shaping. The equipment investment threshold is low, and it is suitable for small and medium batch and trial production scenarios.

[0116] The floating partition adaptive sliding structure is uniformly compatible with the ±5mm module width material tolerance, and can realize one-time synchronous shaping of the length and width of multiple rows of battery cell modules, which greatly improves the consistency of workpiece dimensions after shaping.

[0117] Each embodiment features standardized positioning pin holes on the bottom of the pallet, allowing for precise docking with conveying, positioning, welding, and testing equipment, enabling continuous process flow and reducing transfer and positioning losses.

[0118] The device is easy to assemble and disassemble, and the clamps, partitions, and pads can all be replaced and maintained individually. It can be adapted to the shaping and processing of various single / multi-row and different size and specification battery cell modules, and has a wide range of applications, taking into account both equipment practicality and production economy.

Figure 10As shown, guide rollers 11 are constrained on the inner sides of two sets of steps 21; the base frame 10 is also provided with a stop block 13 and an anti-pinch block 12 on its side, both of which are placed on the steps 21 and are used to support the base frame 10 on the bearing plane; the anti-pinch block 12 is located in the length direction of the base frame 10 and its length is greater than that of the stop block 13, and its length is greater than that of the step 21. Limiting blocks 16 are provided on the side of the base frame 10, such as... Figure 9 The lower side. Figure 9 As an example of pallet conveying on a conveyor line, after the pallet stops moving on the conveyor line by being blocked by a limit block, a lifting and positioning mechanism can be set under the pallet to precisely position the pallet by inserting a positioning pin into the positioning pin hole. Subsequently, it can be used in conjunction with corresponding workstations or equipment to perform processes such as electrode welding of module cells, side plate welding, height measurement of the electrode post, or generation of coordinates of the electrode post relative to the pallet position.

[0122] This invention features anti-pinch blocks and stops installed on the side of the frame, preventing hand pinching and thus possessing practicality.

[0123] Example 3

[0124] like Figure 11-15 This is another embodiment of the present invention, based on embodiment 1, such as... Figure 14 As shown, both the intermediate fixed partition 6 and the floating partition 5 have a two-lobed structure and an internal receiving cavity 52, within which an elastic airbag 53 is installed; the elastic airbag initially... Figure 14 It is vertically elliptical in shape. When squeezed, the top and bottom ends squeeze the corresponding plates and move up and down; the top squeezes the pressure sensor and the bottom squeezes the rising spring.

[0125] A compression hole 54 is provided in the middle of the receiving cavity 52. ​​An elastic plug 55 is installed in the compression hole 54. One end of the elastic plug 55 is inserted into the compression hole 54 and connected to the elastic airbag 53.

[0126] A pressure sensor 56 is installed on the top of the receiving cavity 52, with the detection end facing downwards; the top of the elastic airbag 53 movably abuts against the detection end of the pressure sensor 56.

[0127] like Figure 14 and 15 The bottom of the elastic airbag 53 is provided with a rising plate 57 and a rising spring 58. The bottom of the rising spring 58 is fixedly connected to the bottom of the receiving cavity 52, and the top is fixedly connected to the rising plate 57. The rising plate 57 is connected to the bottom of the elastic airbag 53. The top of the elastic airbag is provided as a position plate and a movable compression pressure sensor. Figure 14 The distance between the elastic plug support plate and the floating partition plate can be changed according to actual use.

[0128] The elastic plug 55 is externally mounted with a support plate 59, which is movably connected to the side of the module housing 15; the extrusion hole 54 is a stepped hole, and a lateral spring 510 is installed between the elastic plug 55 and the stepped surface of the extrusion hole 54.

[0129] In this embodiment, an elastic plug is used to laterally compress each battery cell module via a support plate, forming and maintaining the pressure of the battery cell module. Secondly, during compression, the lateral pressure of two sets of quick-clamping clamps compresses the elastic plug against the position plate located at the top of the elastic airbag, allowing for pressure detection. A remote alarm can also be installed to measure and trigger an alarm, ensuring the pressure does not exceed the limit. Furthermore, the elastic airbag supports the elastic plug and the lateral spring, ensuring that the battery cell module is cushioned during compression and not subjected to concentrated force, thus preventing wear on the surface of the battery cell module and its casing.

[0130] Example 4

[0131] like Figure 16-21 This is another embodiment of the present invention, based on embodiment 1; since the bottom plate of the tray is hoisted by the lifting ring, while embodiment 1 only uses positioning pin holes, it is necessary to continuously align or use external instruments to align the holes before insertion.

[0132] Specifically, the positioning structure also includes a bottom plate 30, which includes an arc-shaped portion 31 and a guide portion 32, such as... Figure 19 As shown, the arc-shaped part 31 and the positioning ring 17 are concentric; a connecting bearing 33 is installed between the arc-shaped part 31 and the positioning ring 17; the arc-shaped part 31 has an opening; the connecting bearing allows the arc-shaped part to rotate after the positioning plate and the base plate frame are disassembled, enabling installation in different directions. When installing in reverse, shims need to be added before bolting to the bottom frame or the bottom plate of the tray to ensure a good connection.

[0133] The guide part 32 is connected to the end of the opening of the arc-shaped part 31; the two sets of guide parts 32 are tapered and a positioning plate 34 is provided between them, and the positioning plate 34 is detachably connected to the base frame 10.

[0134] The positioning rings 17 are provided in four sets and are arranged in a rectangular pattern, such as... Figure 16 As shown, a positioning component is installed at the bottom of the base frame 10. The positioning component is located between two adjacent sets of base plates 30, and its height is not greater than the height of the base plate 30.

[0135] The positioning element includes a positioning cylinder 35, such as Figure 21 As shown, a connecting post 36 is installed inside the positioning cylinder 35. The connecting post 36 is inserted into the arc-shaped part 31 and an abutment plate 37 is installed inside the arc-shaped part 31. The abutment plate 37 is used to abut against the tooling inserted into the positioning pin hole 14.

[0136] like Figure 21 As shown, the connecting column 36 is fitted with a limiting spring 38 inside the positioning cylinder 35, and a flexible shaft 39 is installed at the end of the connecting column 36 away from the abutment plate 37. The flexible shaft 39 is constrained in the middle of the sliding assembly 310 and slides at the bottom of the base plate frame 10.

[0137] During installation, the lower base plate of the pallet is hoisted, then moved to the designated position and lowered until the lower tooling structure is inserted into the guide section. The two sets of guide sections are conical. Then, the lower base plate of the pallet is moved laterally so that the lower tooling is moved to the opening of the arc-shaped section. Then, the flexible shaft is pulled so that the outer wall of the abutment plate fits against the inner wall of the arc-shaped section, thereby moving the lower tooling to the positioning pin hole of the positioning ring. The positioning pin hole is inserted and the flexible shaft is released, so that the two ends of the flexible shaft push the abutment plate against the lower tooling under the reset effect of the limit spring. The side of the abutment plate facing the lower tooling can be set as a high-friction surface to ensure that the lower tooling does not rotate, thereby ensuring that the lower base plate of the pallet does not rotate.

[0138] This invention guides the bottom connecting structure of the support tray to be inserted into the positioning pin by setting a guide part, and constrains the rotation of the lower tooling by moving the abutment plates at both ends by installing a flexible shaft to pull the connecting columns at both ends. The flexible shaft is quickly reset after being pulled by limit springs at both ends.

[0139] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
