Description

Technical Field

[0001] This invention relates to the field of battery module assembly technology, specifically to a clamping and assembling device for multiple battery modules. Background Technology

[0002] With the rapid development of energy storage systems and other fields, the assembly accuracy, efficiency and safety of battery modules have become the focus of industry attention. When assembling batteries, it is usually necessary to clamp multiple battery groups together. In the past, mechanical clamps or manual clamping methods were used. Manual or simple mechanical clamping can easily lead to uneven force on the battery, which may cause cell deformation, electrode damage, or even thermal runaway risk. Therefore, in order to improve the clamping efficiency of battery modules, corresponding clamping assembly devices are usually used.

[0003] Existing battery module clamping devices typically require manual placement of batteries into a tray, followed by clamping using multi-directional clamping fixtures. Since multiple battery groups need to be clamped, spaced partitions are placed on the tray to ensure the sides of each battery group are aligned. During subsequent clamping, the partitions move under the tray and push the batteries on both sides towards the center via a longitudinal clamping structure. However, because the tray is fixed, the bottom of the battery slides against it during this process. Excessive friction can increase the probability of assembly damage.

[0004] Therefore, we propose a multi-group battery module clamping assembly device to solve the problems mentioned above. Summary of the Invention

[0005] The purpose of this invention is to provide a multi-battery module clamping and assembly device to solve the problem mentioned in the background art. Currently available battery module clamping devices typically require manual placement of batteries sequentially into a tray, followed by clamping using a multi-directional clamping fixture. Because multiple battery groups need to be clamped, partitions are placed at intervals on the tray to ensure the sides of each battery group are aligned. During subsequent clamping, the partitions move under the tray and push the batteries on both sides towards the middle battery using a longitudinal clamping structure. However, during this pushing and clamping process, because the tray is fixed, the bottom of the battery slides against the tray at a certain distance. When the battery experiences significant friction, the probability of assembly damage increases.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a multi-group battery module clamping assembly device, comprising a support base and a bearing platform mounted on the upper end of the support base. A first cylinder and a second cylinder are mounted in the transverse direction of the bearing platform, with the telescopic end of the first cylinder connected to a stop portion and the telescopic end of the second cylinder connected to a clamping portion. The stop portion and the clamping portion are located on the left and right sides of the bearing platform. A third cylinder is symmetrically distributed in the longitudinal direction of the bearing platform, with the telescopic end of the third cylinder connected to a contact power portion. The bearing platform consists of multiple mounting seats, each mounting seat having a lifting plate. Adsorption holes are provided on the surface of the lifting plates on the front and rear mounting seats. The lifting plates on the front and rear mounting seats are interconnected via a connecting hose and a vacuum pump. Both front and rear mounting seats are interconnected via auxiliary springs to a slider at the lower end of the lifting plate. The adsorption holes are used to adsorb the battery modules placed on the lifting plates, so that when the battery modules are pushed longitudinally to contact the battery modules on the middle lifting plate, the left and right lifting plates move synchronously with the batteries, maintaining a relatively stationary state.

[0007] Preferably, the mounting base and the support plate in the middle position are fixedly connected, and guide rods are fixed on the support plates on both the front and rear mounting bases. The guide rods pass through the side of the mounting base, and positioning magnetic blocks are embedded in the guide rods. Electromagnets fixed on the mounting base are provided on the side of the positioning magnetic blocks.

[0008] By adopting the above technical solution, the position of the lifting plates on the front and rear mounting seats can be fixed by the magnetic force of the positioning magnetic block on the guide rod after the electromagnet is energized.

[0009] Preferably, the lifting plates on the front and rear sides of the mounting base are hollow inside, and the surface of the lifting plates is evenly distributed with multiple adsorption holes.

[0010] By adopting the above technical solution, when the hollow cavity inside the support plate is affected by negative pressure, the battery module can be adsorbed by the adsorption holes on the surface of the support plate.

[0011] Preferably, the outer wall of the bottom slider of the lifting plate on the front and rear sides of the mounting base is in contact with the inner wall of the mounting base, and the lifting plate and the mounting base form an elastic telescopic structure through the auxiliary spring.

[0012] By adopting the above technical solution, the slider at the bottom of the lifting plate fits into the inner wall of the mounting base, thereby ensuring the stability of the lifting plate during movement. At the same time, the auxiliary spring facilitates the return and rebound of the lifting plate after movement.

[0013] Preferably, the guide rod and the mounting base are slidably connected, and the positioning magnetic block embedded on the guide rod is set to be elongated, and the positioning magnetic block can be attracted by an electromagnet after being energized.

[0014] By adopting the above technical solution, the guide rod can slide on the mounting base, thereby enabling the guide rod to move synchronously with the lifting plate.

[0015] Preferably, the support base has a pin hole near the abutment, and the inside of the pin hole is used to insert a pin to provide the abutment with blocking support force.

[0016] By adopting the above technical solution, when the blocking part is in contact with one side of the battery module, the pin is inserted into the pin hole to avoid excessive clamping force of the subsequent clamping part, which would exceed the limit of the second cylinder and cause the blocking part to move and fail to clamp.

[0017] Preferably, a gap is reserved between adjacent mounting seats, and a lifting cylinder fixed to the support base is provided below the gap. A baffle plate is fixed to the telescopic end of the lifting cylinder, and an adjustment plate is connected inside the baffle plate through a rotating shaft. A transmission gear is fixed on the rotating shaft of the adjustment plate, and a linkage rack is provided on the side of the transmission gear. The linkage rack is fixed to the mounting seat.

[0018] By adopting the above technical solution, the side of the battery module can be placed flush by setting up the baffle plate.

[0019] Preferably, the control plate forms a rotating connection structure through a rotating shaft and a blocking plate, and the transmission gear on the rotating shaft of the control plate can mesh with the linkage rack after contacting it, and a spiral spring that provides a reset elastic force is installed on the outside of the rotating shaft of the control plate.

[0020] By adopting the above technical solution, when the blocking plate moves upward, the transmission gear and the linkage rack come into contact, which enables the transmission gear to drive the control plate to rotate, so that the control plate rotates to a horizontal state, so as to facilitate the placement of battery modules of different widths.

[0021] Preferably, a detection module is installed at the corner of the support base. The detection module is used to detect the positive and negative terminals of the battery module. The detection module is electrically connected to the display screen, which is used to display the positive and negative terminals of the battery module.

[0022] By adopting the above technical solution, the detection module can be set up to measure the positive and negative terminals when the battery modules are placed manually, so as to ensure that the battery modules are placed correctly on the support plate.

[0023] Preferably, the detection module includes a receiving block fixed on a support base, and a limiting plate is installed on the receiving block, with a detection contact mounted on the limiting plate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the multi-group battery module clamping assembly device, by setting a movable base on the tray, after the battery is placed on the base, the negative pressure is used to adsorb the battery. When clamping longitudinally, the battery moves and the base moves synchronously, so that the base and the battery are relatively stationary, reducing the friction between the battery and the base.

[0025] 1. It is equipped with adsorption holes. Through the adsorption holes on the support plate, the battery module can be adsorbed under negative pressure. By adsorbing the battery module, the support plate can move synchronously when the battery module moves longitudinally, so that the support plate and the battery module are relatively stationary, reducing the friction between the battery module and the support plate when the battery module moves longitudinally. At the same time, the adsorption holes on the support plate can also prevent the battery module from shifting due to other factors during the movement.

[0026] 2. An adjustment plate is provided. By opening the lifting cylinder, the blocking plate can be moved upward. The cooperation between the blocking plate and the mounting base can ensure that the sides of the battery module placed on the lifting plate are flush. At the same time, as the blocking plate continues to move upward, the transmission gear and the linkage rack can mesh. The transmission gear drives the adjustment plate to rotate. By rotating the adjustment plate to a horizontal state, the distance between the plate and the side of the mounting base can be reduced, so as to accommodate battery modules of different widths.

[0027] 3. Equipped with detection contacts, the positive and negative terminals of the battery modules are detected by the detection contacts on the limit plate when the worker manually places the battery modules on the lifting plate. The detection results are then transmitted to the display screen for display, so that the worker can perform the detection and place the battery modules correctly when the positive and negative terminals are uncertain.

[0040] 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 skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1-10Existing battery module clamping devices typically require manual placement of batteries into a tray, followed by clamping using multi-directional clamping fixtures. Since multiple battery groups need to be clamped, spaced partitions are placed on the tray to ensure the sides of each battery group are aligned. During subsequent clamping, the partitions move under the tray and push the batteries on both sides towards the center via a longitudinal clamping structure. However, because the tray is fixed, the bottom of the battery slides against it during this process. Significant friction increases the probability of assembly damage. To address this issue... Technical Issue: This embodiment discloses the following technical content: a multi-group battery module clamping assembly device, including a support base 1 and a bearing platform 2 mounted on the upper end of the support base 1. A first cylinder 3 and a second cylinder 5 are mounted in the transverse direction of the bearing platform 2, and the telescopic end of the first cylinder 3 is connected to a stop part 4. The telescopic end of the second cylinder 5 is connected to a clamping part 6. The stop part 4 and the clamping part 6 are located on the left and right sides of the bearing platform 2. A third cylinder 7 is symmetrically distributed in the longitudinal direction of the bearing platform 2, and the telescopic end of the third cylinder 7 is connected to a contact power part 8. The bearing platform 2 is composed of multiple mounting seats 201, and each mounting seat 201 is equipped with a lifting plate 202. The lifting plates 202 on the front and rear mounting seats 201... The surface is provided with adsorption holes 203. The lifting plates 202 on the front and rear mounting bases 201 are connected to each other via connecting hoses 204 and vacuum pumps 205. Both the front and rear mounting bases 201 are connected to the sliders at the lower end of the lifting plates 202 via auxiliary springs 206. The adsorption holes 203 are used to adsorb the battery modules placed on the lifting plates 202, so that when the battery modules are pushed vertically to come into contact with the battery modules on the middle lifting plate 202, the left and right lifting plates 202 move synchronously with the batteries and remain relatively stationary. The mounting base 201 in the middle position is fixedly connected to the lifting plates 202. Guide rods 207 are fixed on the lifting plates 202 on both the front and rear mounting bases 201, and the guide rods 207 pass through the sides of the mounting bases 201. The guide rod 207 is inlaid with a positioning magnet 208, and the side of the positioning magnet 208 is provided with an electromagnet 209 fixed on the mounting base 201. The lifting plates 202 on the front and rear mounting bases 201 are hollow inside, and multiple adsorption holes 203 are evenly distributed on the surface of the lifting plates 202. The support base 1 has a pin hole 9 near the abutment part 4, and the inside of the pin hole 9 is used to insert a pin to provide blocking support for the abutment part 4. The outer wall of the bottom slider of the lifting plate 202 on the front and rear mounting bases 201 is in contact with the inner wall of the mounting base 201, and the lifting plate 202 and the mounting base 201 form an elastic telescopic structure through the auxiliary spring 206. The guide rod 207 and the mounting base 201 are slidably connected.Furthermore, the positioning magnet 208 embedded in the guide rod 207 is elongated, and the positioning magnet 208 can be attracted by the energized electromagnet 209. A space is reserved between adjacent mounting bases 201, and a lifting cylinder 10 fixed to the support base 1 is installed below the space. A baffle plate 11 is fixed to the telescopic end of the lifting cylinder 10.

[0042] When it is necessary to tighten the battery modules, the lifting cylinder 10 is activated, causing the baffle plate 11 to move upwards, extending it out of the mounting base 201. The mounting base 201 and the baffle plate 11 ensure that the battery modules are aligned. After the battery modules are positioned, the lifting cylinder 10 controls the baffle plate 11 to move downwards, retracting it below the mounting base 201. Then, the vacuum pump 205 is activated. The vacuum pump 205, through the connecting hose 204, creates a negative pressure inside the lifting plate 202, thereby utilizing… The suction holes 203 on the lifting plate 202 suction and fix the placed battery module. By suctioning the battery module, the lifting plate 202 and the battery module are first integrated. Simultaneously, the suction-fixed battery module prevents displacement during its movement. The third cylinder 7 is activated, causing the contact power unit 8 to move towards the battery module. After contacting the battery module, the contact power unit 8 pushes it closer to the battery module on the central lifting plate 202. The movement of the battery module causes the lifting plate 202 to move synchronously, ensuring its proper functioning. The battery module and the support plate 202 are in a relatively static state to reduce friction between the battery module and the support plate 202 during longitudinal pushing, which could damage the battery module. After longitudinal contact is completed, the electromagnet 209 is turned on. When the electromagnet 209 is energized, it can attract the positioning magnet 208 on the side guide rod 207 of the support plate 202, thereby fixing the position of the support plate 202. Then, the vacuum pump 205 is turned off to restore the positive pressure state inside the support plate 202, and the suction hole 203 on the support plate 202 releases the suction of the battery module. Note that because the lifting plate 202 is limited by the magnet at this time, it will not reset and rub against the battery module. The first cylinder 3 is activated so that the blocking part 4 of the extension end of the first cylinder 3 is in contact with one side of the battery module. Then, the pin is inserted into the pin hole 9 to block the blocking part 4. Then, the second cylinder 5 is activated. After the second cylinder 5 is activated, the clamping part 6 can move towards the battery module, thereby clamping the battery module laterally. After the battery is clamped in multiple directions, it is convenient to assemble the battery module housing.

[0043] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above. The following technical content is disclosed in this example: Figures 2-7and Figure 10 As shown, the inside of the blocking plate 11 is connected to the control plate 12 via a rotating shaft. A transmission gear 13 is fixed on the rotating shaft of the control plate 12, and a linkage rack 14 is provided on the side of the transmission gear 13. The linkage rack 14 is fixed on the mounting base 201. The control plate 12 and the blocking plate 11 form a rotating connection structure through the rotating shaft. After the transmission gear 13 on the rotating shaft of the control plate 12 contacts the linkage rack 14, they can mesh and transmit power. A spiral spring that provides a reset elastic force is installed on the outside of the rotating shaft of the control plate 12.

[0044] When it is necessary to clamp the battery module, the lifting cylinder 10 controls the blocking plate 11 to move upward, so that the blocking plate 11 extends out of the mounting base 201. With the action of the blocking plate 11 and the mounting base 201 with an "L"-shaped longitudinal section, the sides of the battery modules placed in sequence can be made flush with each other. When it is necessary to clamp the battery module of another width, the lifting cylinder 10 continues to control the blocking plate 11 to move upward. After the blocking plate 11 moves upward, the transmission gear 13 and the linkage rack 14 can mesh with each other. At this time, the transmission gear 13 drives the control plate 12 to rotate, so that the control plate 12 rotates from the vertical state to the horizontal state. By rotating the control plate 12 to the horizontal state, the distance between the control plate 12 and the side of the mounting base 201 can be shortened, thereby facilitating the placement of battery modules of another width.

[0045] like Figure 2 and Figure 11 As shown, a detection module 15 is installed at the corner of the support base 1. The detection module 15 is used to detect the positive and negative terminals of the battery module. The detection module 15 is electrically connected to the display screen 16, which is used to display the positive and negative terminals of the battery module. The detection module 15 includes a receiving block 151 fixed on the support base 1, and a limiting plate 152 is installed on the receiving block 151. A detection contact 153 is installed on the limiting plate 152.

[0046] When a worker places a battery module onto a lifting plate 202, the positive and negative terminals of the battery module can be placed against the detection contact 153 on the limiting plate 152. The detection contact 153 detects the positive and negative terminals of the battery module and transmits the detection results to the display screen 16 for display. This allows workers to correctly place the battery module if they are unsure of its positive and negative terminals.

[0047] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0048] 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.
