Based on this, chinese patent CN207675894U discloses a drawer type battery detection device, which includes a needle bed mechanism, where the needle bed mechanism includes an upper fixing frame, an upper detection needle group, a lower detection needle group, an upper detection plate, a middle supporting plate, a fixing base, and a plurality of guide pillars, the upper fixing frame, the upper detection plate, the middle supporting plate, and the fixing base are connected through the guide pillars, the upper detection needle group is arranged downward on the upper detection plate, the lower detection needle group is arranged upward on the fixing base, the middle supporting plate is arranged between the upper detection plate and the fixing base, the upper detection plate is provided with a lifting mechanism, and the fixing base is connected with the lifting mechanism; the middle supporting plate is provided with a battery tray, the middle supporting plate is provided with a first detection hole group corresponding to the lower detection needle group, the battery tray is provided with a second detection hole group matched with the first detection hole group, sliding grooves are formed in two sides of the middle supporting plate, and sliding blocks matched with the sliding grooves are arranged in two sides of the battery tray. The drawer type battery detection device has the advantages of simple positioning mechanism and accurate positioning.
However, the drawer-type battery detection device disclosed above has a technical problem that it is difficult to standardize. Specifically, the working principle of the drawer-type battery detection device disclosed above is as follows: firstly, pulling a handle of a battery tray to pull the battery tray out, placing a battery plastic sucking disc filled with batteries on the battery tray and pushing the battery plastic sucking disc back through accurate positioning of a positioning convex groove and a positioning groove, starting a battery detection device, simultaneously starting an electric fan set to radiate heat of a detection set, pressing down by a return stroke of an air cylinder to drive a middle supporting plate to move downwards together, and accurately reaching a detection position by an upper detection set and a lower detection set under the limiting action of an upper limiting column and a lower limiting column to detect the batteries. During detection, a worker can load a new battery blister tray with a battery, after the battery blister tray is detected to be finished, the cylinder of the lifting mechanism acts, the upper detection plate resets, the reset mechanism enables the middle supporting plate to be combined, the battery tray is pulled out, and the next battery blister tray is replaced. Therefore, when the drawer type battery detection device is used for detecting a battery, the positioning convex groove and the positioning concave groove are required to be matched with the battery to be detected, so that the battery can be detected conveniently; if the shape or structure of the battery to be detected is changed, the related mechanism needs to be redesigned; therefore, it is difficult to standardize the drawer type battery test device. In addition, because the square battery needle bed of the traditional conveyor line butt joint feeding is in butt joint with the conveyor line of incoming materials by using a section of roller line, the tray is jacked in a gap between the roller and the roller after the battery tray enters in place, so that the battery pole and the probe of the upper needle bed assembly are pressed and conducted to realize the test of the battery, and the mode can not be realized in the flying needle occasions requiring the translation of the tray to realize the step-by-step test and the occasions requiring the probe pressing up and down such as cylindrical batteries and the like. Because, for the occasion of the cylindrical battery and the flying probe test, a needle bed with larger structure difference and complexity is additionally adopted, the standardization, the cost control and the design period of the equipment component are all affected adversely.

Specifically, please continue to refer to fig. 6; as shown in fig. 6, a battery tray 4 is movably arranged between the tray supporting plate component 2 and the upper needle bed component 3; the battery tray 4 can bear a battery to be detected and connects the tray pallet assembly 2 with an external battery transmission line. More specifically, when the battery detection needle bed is in a working process, the battery tray 4 filled with batteries to be detected is transferred to the tray pallet component 2 by an external battery transmission line; at this time, the tray pallet assembly 2 is located at the initial position, and the tray positioning pins 208 disposed on the transfer board 205 clamp and connect the battery tray 4 to the transfer board 205; the two side action parts of the transfer cover plate chain component 102 arranged on the needle bed base component 1 are in power connection with the battery tray 4, so that the transfer cover plate chain component 102 continues to act on the battery tray 4 to trigger a sensor component 207 arranged in the middle of the supporting plate square frame 201; thus, the sensor assembly 207 issues a command to decelerate the transfer lid chain assembly 102; then, the battery tray 4 continues to operate until its edge abuts against the stopper plate 203; in addition, when the battery tray 4 just enters the tray supporting plate assembly 2, the two guiding bars 202 disposed on the two sides of the supporting plate square frame 201 guide the battery tray 4. Then, after the battery tray 4 moves to a mechanical limit, the sensor assembly 207 arranged at the end of the pallet square frame 201 establishes a bin and confirms that the battery tray 4 is in place, and the scanning assembly 206 reads the bar code information above the battery tray 4; then, the two pressing cylinders 304 simultaneously move the pallet square through frame 201 together with the battery tray 4 upward under the limit guidance of the guide rods 305, and the linear bearings 204 facilitate the guidance of the guide rods 305 to make the upward movement of the pallet square through frame 201 smooth; and the supporting plate square through frame 201 ascends until the pole of each battery to be tested is correspondingly conducted with one probe 303a; then, the detection of the preset parameters of the battery is completed. After the detection is finished, the pressing air cylinder 304 drives the supporting plate square through frame 201 again to reset; then, the battery tray 4 is driven by the transfer cover chain assembly 102 to be discharged to a battery conveyor line returning to the outside, and thus, a battery inspection process is completed. More specifically, the length and width dimensions of the base square through frame 101, the supporting plate square through frame 201 and the upper needle bed square through frame 301 can be freely adjusted, so that the tray supporting plate assembly 2 can be adapted to the battery trays 4 with different specifications, and the battery detection needle bed has the advantage of universality.
Further, the transfer cover plate chain assembly 102 has a speed-regulating speed-reducing motor 102a, two U-shaped cover plate chains 102b and a transmission shaft 102c; the speed-regulating and speed-reducing motor 102a is arranged between the two U-shaped cover plate chains 102b and is connected to the base square through frame 101; and the speed-regulating and speed-reducing motor 102a is simultaneously in transmission connection with the two U-shaped cover plate chains 102b through the transmission shaft 102 c. Specifically, the speed-regulating and speed-reducing motor 102a and the two U-shaped cover plate chains 102b are respectively connected to the base square through frame 101, and the speed-regulating and speed-reducing motor 102a is simultaneously and dynamically connected to the two U-shaped cover plate chains 102b through a transmission shaft 102, so that when the battery tray 4 is placed on the pallet square through frame 201, the two U-shaped cover plate chains 102b are respectively located at two sides of the battery tray 4 and are in power connection with the battery tray 4; therefore, the speed-regulating and speed-reducing motor 102a can drive the battery tray to perform corresponding actions in the tray supporting plate assembly 2.
Further, the tray and pallet assembly 2 further has a stepping motor 209, a plurality of linear sliders 210, and the linear guide 211. The stepping motor 209 is fixedly connected to the supporting plate square through frame 201, and the stepping motor 209 is in power connection with the transfer plate 205 through a screw rod; the plurality of linear sliding blocks 201 are respectively arranged at the bottom of the moving and carrying plate 205, and each linear sliding block 210 is movably connected with the linear guide rail 211; the linear guide rail 211 is fixedly connected to the supporting plate square through frame 201. In particular, in another embodiment of a battery detection needle bed according to the invention; distributed flying probe detection is required for the square battery; the specific working process comprises the following steps: an external conveying line transfers the battery tray 4 filled with batteries into the tray pallet assembly 2, and the battery tray 4 is driven by the transfer cover plate chain assembly 102 to move in place; then, the scanning component 206 reads information such as a bar code of the battery tray 4; then, the pressing cylinder 304 drives the tray supporting plate assembly 2 to ascend, and the poles of the first group of batteries to be tested are detected after the probe 303a is conducted. Then, the pressing cylinder 304 drives the tray and pallet assembly 2 to descend to a preset middle position height, and then the stepping motor 209 drives the transfer plate 205 to translate for a battery distance along the guidance of the linear slider 210 and the linear guide rail 211 through a lead screw; then, the tray and pallet assembly 2 moves upward to a preset battery detection station under the driving of the pressing cylinder 304. Specifically, the processes of completing primary battery detection, descending to the middle position, performing translation adjustment, and ascending to the battery detection station may be repeated for multiple times until all detection requirements of the entire tray of batteries are completed, and then the battery tray 4 is released onto an external conveyor line.
Further, for the detection situation of the cylindrical battery that needs to be detected both at the top and the bottom, in other embodiments, a lower probe (not shown) may be installed on the pallet square frame 201; the lower probe has the same structure as the probe 303a, but is disposed on the pallet square frame 201. Therefore, the upper side and the lower side of the partial cylindrical battery can be simultaneously detected.
Further, the probe module 303 further has a plurality of probe accommodating frames 303b and a plurality of probe damping springs 303c; the plurality of probe accommodating frames 303b are uniformly arranged on the upper needle bed square through frame 301, the plurality of probes 303a are arranged at the bottom of the probe accommodating frames 303b, and a probe damping spring 303c is correspondingly arranged between each probe 303a and the probe accommodating frame 303 b. Specifically, a plurality of the probe accommodating frames 303b are uniformly arranged below the upper needle bed square through frame 301, and a plurality of the probes 303a are arranged at the bottom of each probe accommodating frame 303 b; then, each probe 303a is connected with a probe damping spring 303c between the probe accommodating frames 303 b; therefore, when the probe 303a is close to the battery product to be detected, the probe 303a is prevented from being damaged due to impact force.
Specifically, the battery detection needle bed has the beneficial effects that: because the existing battery detection needle bed which is in butt joint with a conveying line and automatically feeds has the disadvantages of complex structure and poor adaptability, the difference between the needle bed structures designed according to different battery specifications or different detection modes is large. Therefore, it is difficult for the installation and debugging personnel to quickly know the installation and debugging of the needle bed of the new project by taking advantage of the capability of one-to-three or touch bypass, thereby causing various production problems caused by improper installation and debugging. The battery detection needle bed structure can adapt to various battery tray structures or can be used in a new project through simple adjustment, standardized inventory can be realized for most parts, the design efficiency of the new project is improved by 20-50%, the manufacturing cost is reduced by 5-20%, and the problems of installation and debugging are reduced by 2-10%.
