Fig. 1 is a plan view of a battery module 10 that is inspected by the inspection apparatus according to the present disclosure. As shown in fig. 1, a battery connection system (CCS) is overlaid over a plurality of battery cells, and the CCS is electrically connected to each battery cell through a welding point P0. Therefore, the cells are connected in series and in parallel by the CCS in a predetermined manner to achieve charging and discharging of energy. However, poor welding phenomena such as missing welding, desoldering, too wide welding seam, etc. may occur during the welding process, and thus the welding condition of each welding point P0 needs to be detected.

The inspection apparatus in the present disclosure inspects the solder joint condition by performing resistance inspection on the battery module 10. Resistance detection is performed by contact resistance measurement in the present disclosure. Specifically, the inspection apparatus inspects whether the solder joint quality is acceptable by contacting the contact probe 50 with the measurement point P1 directly above and the measurement point P2 directly below the solder joint P0 shown in fig. 1, thereby switching in voltages at the measurement points P1 and P2 and measuring a voltage drop between the measurement points P1 and P2. More specifically, the present disclosure employs a 4-wire measurement method to detect solder joint quality.

It should be understood that the sensing apparatus in the present application is not limited to sensing the resistance of the battery module, but may sense, for example, other parameters such as voltage, current, temperature, flatness, etc. of the battery module as needed.

Fig. 2 is a perspective view of the inspection apparatus 20 for a battery module according to the present disclosure. The detection device comprises an upper box body and a lower box body. The upper case includes an upper frame 200. The upper frame 200 is provided with a front operation door 201 and a left operation door 202 (shown in fig. 3). The front operation door 201 and the left operation door 202 are each configured to be detachable or openable and closable. The upper box body is further provided with a safety lock 203, the safety lock 203 is arranged on the upper frame 200, the safety lock 203 is configured to disconnect the circuit input from an electrical cabinet (not shown, arranged outside the detection device) to the resistance detector when the operator opens the front operation door 201, stop detection, and connect the circuit input from the electrical cabinet to the resistance detector only when the current operation door 201 is closed. The safety lock 203 can prevent damage or injury to an operator or an external device due to high voltage during detection. The upper box also includes a vent 204 to allow air exchange with the outside air by the detection apparatus. Fig. 4 shows a perspective view of the lower box. The lower case includes a lower frame 210, the lower frame 210 accommodating a resistance detector 211 therein, the resistance detector 211 being capable of detecting the resistance of the battery module through contact of the contact probe with the CCS and analysis of data.

Fig. 3 is a perspective view of an upper case of the inspection apparatus for the battery module according to the present disclosure. In fig. 3, the battery module 10 is supported on the pallet 11 for easy transportation and positioning, and at this time, the battery module 10 and the pallet 11 fixed together are moved inside the inspection equipment 20 to be inspected. The trays 11 facilitate the transportation and positioning of the battery module 10. In the present disclosure, the battery module 10 and the tray 11 are moved from the left side in fig. 3 to the inside of the inspection apparatus 20, and when moving, the left operating door 202 is opened and the battery module 10 and the tray 11 are pushed into the inside of the inspection apparatus 20 from the left side by an operator or other equipment, and then the left operating door is closed when the battery module 10 and the tray 11 are moved in place. The front operating door 201 is shown in an open state in fig. 3. Further, a contact probe moving mechanism 30 and a battery module carrying mechanism 40 of the inspection apparatus 20 are also shown in fig. 3. As shown in fig. 1, the battery module 10 includes a plurality of pads P0, and thus it is necessary to detect each pad, and the contact probe moving mechanism 30 is configured to move the contact probe in six directions, up, down, front, rear, right, and left, to detect each pad. The movement of the contact probe moving mechanism 30 may be performed manually by an operator, for example, who controls the contact probe moving mechanism to move above each solder point through an observation window by an external controller for inspection. It is preferable that the operator should be programmed in advance by an external controller based on the position information of each welding point on the battery module so that the contact probe moving mechanism 30 can automatically move to measure each welding point. The contact probe moving mechanism 30 will be described later with reference to fig. 5. In fig. 3, the battery module 10 and the pallet 11 are integrally supported on the battery module support mechanism 40. The battery module carrying mechanism 40 is configured to not only facilitate the transportation of the battery modules 10 and the trays 11, but also effectively position and protect the battery modules 10 and the trays 11. The battery module carrying mechanism 40 is fixed to the lower case 210, and specifically covers the upper surface of the lower case 210. The battery module carrying mechanism 40 will be described later with reference to fig. 6.

Fig. 5 is a perspective view of the contact probe moving mechanism 30 of the inspection apparatus according to the present disclosure. As shown in fig. 5, the contact probe moving mechanism 30 includes a first direction moving mechanism 301, a second direction moving mechanism 302, and a third direction moving mechanism 303. In the present disclosure, the first direction, the second direction, and the third direction intersect, respectively. More specifically, the first direction, the second direction, and the third direction are perpendicular to each other, and are the z direction, the y direction, and the x direction shown in fig. 3, that is, the up-down direction, the front-back direction, and the left-right direction, respectively. The contact probe 50 can perform contact and separation with the pad by the first direction moving mechanism 301. The contact probe 50 can be moved between different rows of pads by the second direction moving mechanism 302. The contact probe 50 can be moved between different pads of the same row by the third direction moving mechanism. In the present application, the first direction moving mechanism, the second direction moving mechanism and the third direction moving mechanism form a nested configuration with each other, so that the entire contact probe moving mechanism is reduced in volume and simpler in structure.

As illustrated in fig. 5, the first direction moving mechanism 301 includes a first moving member 3010 and a first base portion 3011. The first moving member 3010 can move up and down along the first base portion 3011 in a first direction (e.g., the z direction in this disclosure). In the present disclosure, a recess is provided on the first base portion 3011, and a protrusion engaged with the recess is formed on the first moving member 3010, so that the recess of the first base portion 3011 can guide the protrusion of the first moving member 3010. Further, it is to be understood that the protrusions may also be provided on the first base portion 3011 and the recesses on the first moving member 3010. Further, other guiding means than the convex-concave fitting structure, such as a lead screw, etc., may be employed. The contact probe 50 is fixed at the lower end portion of the first moving member 3010, and can move up and down following the first moving member. The contact probe 50 has two probe heads, and the two probe heads can be brought into contact with the measurement points P1 and P2, respectively. In the present disclosure, the first power source 3012 is fixed on the first base 3011 and is capable of transmitting movement to the first moving member 3010. Preferably, the first power source in the present disclosure is an electric cylinder, by which the transmission of motion can be performed very accurately, and the volume of the electric cylinder is small. It should be understood that other power sources, such as cylinders, etc., may be used as desired by those skilled in the art. In the present disclosure, the outer contour of the first base portion is formed into a substantially rectangular parallelepiped, and the first power source 3012, which is an electric cylinder, is formed into a substantially L-shape, and therefore the first power source 3012 is snapped onto the outer contour of the first base portion 3011, so that the entire volume of the first direction moving mechanism is small. In fig. 5, the first power source is engaged above the first base 3011, but it should be understood that the first power source may be engaged at other positions as needed. The first direction moving mechanism 301 further includes a cooling device 3013. The cooling device 3013 is configured to cool the contact probe 50 when the contact probe 50 detects the solder joint, so as to avoid overheating the contact probe or the solder joint. In the present disclosure, the cooling device 3013 is connected to a cooling air source through an air tube, and blows air to the contact probe 50 to cool down. Therefore, the cooling device 3013 is disposed at the same end of the first moving member 3010 as the contact probe 50, and the nozzle is directed toward the contact probe 50.

The second-direction moving mechanism 302 includes a second moving member 3020 and a second base 3021. The second moving member 3020 is movable back and forth along the second base 3021 in a second direction (e.g., y-direction in this disclosure). Similarly to the first direction moving mechanism 301, in the present disclosure, a concave portion is provided on the second base 3021, and a protrusion that engages with the concave portion is formed on the second moving member 3020, so that the concave portion of the second base 3021 can guide the protrusion of the second moving member 3020. Further, it is to be understood that the projection may be provided on the second base 3021 and the recess on the second moving piece 3020. Further, other guiding means than the convex-concave fitting structure, such as a lead screw, etc., may be adopted. In the second direction moving mechanism, a second power source (not shown) is also configured as an electric cylinder, and is snappingly fixed to the second base 3021, and is capable of transmitting the movement to the second moving member 3020. It should be understood that other power sources, such as cylinders, etc., may be used as desired by those skilled in the art. Similarly to the first direction moving mechanism 301, the outer contour of the second base portion 3021 is also formed into a substantially rectangular parallelepiped, and the second power source, which is an electric cylinder, is also formed into a substantially L-shape, so that the overall volume of the second direction moving mechanism is small. Further, as shown in fig. 5, the second moving member 3020 of the second direction moving mechanism 302 and the first base portion 3011 of the first direction moving mechanism 301 are formed integrally, and may be manufactured directly as one piece or as separate parts and then assembled together, for example. Further, the second moving piece 3020 of the second direction moving mechanism 302 is fixed to a side portion of the first base portion 3011 of the first direction moving mechanism 301 which is opposite to the first moving piece 3010 in the x direction. Thereby, the second-direction moving mechanism 302 can finally move the contact probe 50 fixed to the first moving member 3010 in the y direction. The second direction moving mechanism 302 further includes a tow chain 3012, and the tow chain 3012 is used for accommodating and protecting, for example, an air pipe of a cable.

The third direction moving mechanism 303 includes a third moving member 3030 and a third base 3031. The third moving member 3030 is movable along the third base 3031 in a third direction (e.g., the x-direction in this disclosure). Similarly to the first direction moving mechanism 301, in the present disclosure, a concave portion is provided on the third base 3031, and a protrusion engaged with the concave portion is formed on the third moving member 3030, so that the concave portion of the third base 3031 can guide the protrusion of the third moving member 3030. Further, it is to be understood that a protrusion may be provided on the third base 3031 and a recess may be provided on the third moving member 3030. Further, other guiding means than the convex-concave fitting structure, such as a lead screw, etc., may be employed. In the third direction moving mechanism, a third power source (not shown) is also configured as an electric cylinder, and is snappingly fixed to the third base 3031, and is capable of transmitting the movement to the third moving member. It should be understood that other power sources, such as cylinders, etc., may be used as desired by those skilled in the art. Similarly to the first direction moving mechanism 301, the outer contour of the third base 3031 is also formed in a substantially rectangular parallelepiped, and the third power source which is an electric cylinder is also formed in a substantially L-shape, so that the entire volume of the third direction moving mechanism is small. Further, as shown in fig. 5, the third moving member 3030 of the third direction moving mechanism 303 and the first base portion 3011 of the second direction moving mechanism 302 are formed integrally, and may be manufactured directly as one piece or as separate parts and then assembled together, for example. Further, the second base 3021 of the second direction moving mechanism 302 is fixed to a side portion of the third moving member 3030 of the third direction moving mechanism 303 opposite to the third base 3031 in the z direction. Thereby, the third direction moving mechanism 303 can finally move the contact probe 50 fixed to the first moving member 3010 back and forth in the x direction. The third direction moving mechanism 303 further includes a tow chain 3012, and the tow chain 3012 is used to house and protect, for example, an air pipe of a cable. By integrating the second moving member 3020 of the second direction moving mechanism 302 and the first base portion 3011 of the first direction moving mechanism 301, and integrating the third moving member 3030 of the third direction moving mechanism 303 and the first base portion 3011 of the second direction moving mechanism 302, the first direction moving mechanism 301, the second direction moving mechanism 302 and the third direction moving mechanism 303 are formed in a nested structure in relation to each other, so that the contact probe moving mechanism 30 is more compact in size and simpler in structure. Further, by fixing the second moving member 3020 of the second direction moving mechanism 302 to the side portion of the first base portion 3011 of the first direction moving mechanism 301 which is opposite to the first moving member 3010 in the x direction and fixing the second base portion 3021 of the second direction moving mechanism 302 to the side portion of the third moving member 3030 of the third direction moving mechanism 303 which is opposite to the third base portion 3031 in the z direction, the volume of the contact probe moving mechanism 30 can be made more compact and the structure can be made simpler.

Fig. 6 is a perspective view of the contact probe moving mechanism 30 and the battery module carrying mechanism 40 of the inspection apparatus according to the present disclosure. As shown in fig. 6, the contact probe moving mechanism 30 is supported on the battery module carrying mechanism 40 by two columns.

The battery module carrying mechanism 40 includes a base plate 401, rollers 402, a front blocking mechanism 403, a rear cushion mechanism 404, a rear blocking member 405, a positioning member 406, and a guide member 407. The rolling member 402, the front blocking mechanism 403, the rear cushion mechanism 404, the rear blocking member 405, the positioning member 406, and the guide member 407 are disposed on the base plate 401.

As shown in fig. 6, a plurality of rolling members 402 are provided on the base plate 401, and the rolling members 402 serve to reduce frictional resistance when the battery module 10 and the pallet 11 are transferred onto the base plate 401, facilitating the transfer. The rolling members 402 are configured to protrude slightly beyond the upper surface of the base plate 401 and can start to slide when contacting the moving pallet 11 to reduce frictional resistance.

The front blocking mechanism 403 is located at an upstream end portion of the base plate 401 in the x direction (the moving direction of the battery module 10 and the pallet 11), and a through portion is opened at a corresponding position of the base plate 401 so that the front blocking mechanism 403 can move up and down through the through portion. The front blocking mechanism 403 serves to guide the movement of the battery module 10 and the tray 11 when the battery module 10 and the tray 11 are initially transported, and to limit the battery module 10 and the tray 11 from moving in the opposite direction when the battery module 10 and the tray 11 pass over the front blocking mechanism 403. The front blocking mechanism 403 includes a guide 4030, a pulley 4031, and a cylinder 4032. The upper surface of the guide 4030 is provided as a slope, and a lower end portion of the slope is closer to an upstream end portion of the substrate 401 in the x direction and is provided not higher than the upper surface of the substrate 401. The pulley 4031 is provided at a high end of the slope, that is, closer to a downstream side end of the substrate 401 in the x direction, and the pulley 4031 can roll when contacting the moving pallet 11. The guide 4030 and the pulley 4031 can move up and down in the cylinder 4032 through a shaft (not shown) connected to a lower end portion. Within the cylinder 4032 is provided a buffer, such as a compression spring or an air spring. When the guide 4030 and the pulley 4031 receive pressure from the battery module 10 and the shoe 11 above, they compress the cushioning members in the cylinder 4032 and move downward to the lowered position, thus guiding the movement of the battery module 10 and the shoe 11. And when the battery module 10 and the tray 11 move over the front blocking mechanism 403, the guide 4030 and the pulley 4031 move upward to return to the original position (the position where no external force is applied from above), and due to the slope shape of the guide 4030, the reverse movement of the battery module 10 and the tray 11 is blocked.

The rear cushion mechanism 404 is located at the downstream-side end of the base plate 401 in the x direction (the moving direction of the battery modules 10 and the pallet 11). The rear cushion mechanism 404 includes a cushion head 4040 and a cushion cylinder 4041, and a cushion member such as an air spring is provided in the cushion cylinder 4041. The buffer head 4040 is made of a material, such as rubber, having a hardness lower than that of the battery modules 10 and the pallet 11, and will first contact the rear buffer mechanism 404 when the battery modules 10 and the pallet 11 move in the x-direction toward the end point, thereby causing the buffer head 4040 to move in the buffer cylinder 4041 to compress the buffer member, thereby slowing the movement speed of the battery modules 10 and the pallet 11 and avoiding possible collision damage.

The rear stopper 405 is disposed substantially side by side with the rear cushion mechanism 404 in the y direction, but the upstream end of the rear stopper 405 in the X direction is located behind the upstream end of the rear cushion mechanism 404 in the X direction to avoid collision with the battery module 10 and the pallet 11 before the rear cushion mechanism 404 sufficiently cushions the battery module 10 and the pallet 11. The rear stopper 405 serves to restrict further movement of the battery module 10 and the tray 11 in the x direction.

The positioning member 406 is configured to cooperate with the positioning device on the supporting plate 11 to fix the battery module 10 and the supporting plate 11 after the battery module 10 and the supporting plate 11 are moved to the proper position, for example, the positioning member 406 and the supporting plate 11 may be provided with corresponding through holes or threaded holes for positioning by positioning pins or bolts. The guides 407 are provided in pairs in the y-direction to guide the battery modules 10 and the trays 11 when they are moved in the x-direction.

Consequently, through this disclosed battery module bearing mechanism 40, not only can be convenient for carry out accurate, laborsaving and safe transportation to battery module 10 and layer board 11, can also carry out spacing and positioning action to battery module 10 and layer board 11, convenient follow-up detection through contact probe 50.

Although exemplary embodiments of the present disclosure have been described, it will be understood by those skilled in the art that various changes and modifications can be made to the exemplary embodiments of the present disclosure without substantially departing from the spirit and scope of the present disclosure.
