[0033] The following will illustrate the implementation methods of the utility model in conjunction with the drawings in the specification. It should be noted that the implementation methods involved in this specification are not exhaustive and do not represent the only implementation methods of the utility model. The following corresponding embodiments are only for the purpose of clearly illustrating the utility model content of the utility model patent, and are not intended to limit its implementation methods. For ordinary technicians in this field, different forms of changes and modifications can be made on the basis of the description of this embodiment. All obvious changes or modifications that belong to the technical concept and utility model content of the utility model are also within the scope of protection of the utility model.

[0034] Example 1

[0035] like Figure 1 As shown, an embodiment of the present application provides a transducer cell assembly tool, including a frame 1100 , a positioning seat 1200 , a screwing head 1300 , a rotating mechanism 1400 and a lifting mechanism 1500 .

[0036] The assembly tool provided in this embodiment is applicable to a transducer cell of a certain specification, such as Figure 8 and Fig. 9 As shown, the transducer cell 2 of this specification is composed of a base 21 and a cell body 22, the base 21 has a tubular portion 21a and a disc portion 21b, the cell body 22 is composed of a stud 22a, a plurality of ceramic sheets 22b, a plurality of conductive sheets 22c and a nut 22d, the circumferential surface of the tubular portion 21a has a pair of centrally symmetrical clamping grooves 21a-1, the outer diameters of the ceramic sheets 22b and the conductive sheets 22c are the same and smaller than the outer diameter of the disc portion 21b, a plurality of ceramic sheets 22b and a plurality of conductive sheets 22c are concentrically stacked on the stud 22a, specifically, a conductive sheet 22c is arranged between adjacent ceramic sheets 22b, each conductive sheet 22c has a connector 22c-1, after the transducer cell 2 is assembled, the connectors 22c-1 of adjacent conductive sheets 22c need to satisfy a predetermined positional relationship, in this embodiment, the connectors 22c-1 of adjacent conductive sheets 22c need to satisfy an angle of 180 degrees.

[0037] like Figure 1 and Figure 2As shown, the rack 1100 includes a back plate 1110, a bottom plate 1120 and a sliding plate 1130. The front of the back plate 1110 has two sliding rails 1111 in the up and down directions. The two sliding rails 1111 are arranged at intervals along the left and right directions of the back plate 1110. The bottom plate 1120 is fixed to the lower end of the back plate 1110, and the sliding plate 1130 is set on the two sliding rails 1111 to slide up and down.

[0038] The positioning seat 1200 is used to position the transducer battery cell 2. Figure 3 As shown, the positioning seat 1200 includes a base 1210 , a block 1220 and an upper cover 1230 .

[0039] The chassis 1210 is fixed to the bottom plate 1120 by bolts, and the block 1220 is fixed to the chassis 1210. Figure 4 As shown, the block 1220 has a receiving hole 1221 formed vertically downward from the center of its upper surface for vertically inserting the transducer cell 2 downward.

[0040] The receiving hole 1221 is divided into an upper section and a lower section. The aperture of the upper section is the same as the outer diameter of the disc-shaped portion 21b of the transducer core 2, and the aperture of the lower section is the same as the outer diameter of the tubular portion 21a of the transducer core 2. Figure 5 As shown, a support step 1221a is formed at the intersection of the upper section and the lower section for supporting the disc-shaped portion 21b of the transducer core 2. When the transducer core 2 is inserted into the receiving hole 1221, a gap is formed between the ceramic sheet 22b and the wall of the receiving hole 1221.

[0041] The block 1220 has a first positioning structure and a second positioning structure. The first positioning structure is used to constrain the transducer core 2 to prevent it from rotating, and the second positioning structure is used to limit each connector 22c-1 to a predetermined position.

[0042] Among them, Figure 3 As shown, the first positioning structure includes a pin hole 1222 formed in the front-to-back horizontal direction on the block 1220 and a pin 1223 used to be horizontally inserted into the pin hole 1222 in the front-to-back direction. The pin 1223 includes a handle 1223a and a pair of clamping arms 1223b in the front-to-back direction. The pair of clamping arms 1223b are arranged at intervals on the left and right and are fixed to the handle 1223a. The inner spacing of the pair of clamping arms 1223b is the same as the inner spacing of the pair of clamping grooves 21a-1. After the pair of clamping arms 1223b are inserted into the pin hole 1222, they just clamp the transducer cell 2 on the left and right sides at the pair of clamping grooves 21a-1, thereby restraining the transducer cell 2 to prevent it from rotating.

[0043] like Figure 4 and Figure 5As shown, the second positioning structure includes two positioning grooves 1224 formed on the inner wall of the accommodating hole 1221, and the two positioning grooves 1224 are symmetrically arranged front to back. Each positioning groove 1224 is radially outward and extends downward from the upper surface of the block 1220. The width of the positioning groove 1224 is adapted to the width of the connector 22c-1. Therefore, after the transducer cell 2 is inserted into the accommodating hole 1221, the adjacent connectors 22c-1 must meet a 180-degree angle, thereby realizing the limitation of each connector 22c-1.

[0044] like Figure 3 and Figure 7 As shown, the center position of the upper cover 1230 has a guide hole 1231 in the up and down directions for guiding the screwing head 1300. The guide hole 1231 is concentric with the accommodating hole 1221. A sleeve 1232 is formed on the lower side of the upper cover 1230. The inner diameter of the sleeve 1232 is the same as the outer diameter of the ceramic sheet 22b. The outer diameter of the sleeve 1232 is the same as the inner diameter of the upper section of the accommodating hole 1221. Therefore, the sleeve 1232 can be inserted between the transducer core 2 and the accommodating hole 1221 to fix the upper cover 1230. The sleeve 1232 forms two notches 1232a extending upward from its lower end. The two notches 1232a are symmetrically arranged front to back and correspond radially to the two positioning grooves 1224 front to back. The notch 1232a is for the corresponding connector 22c-1 to pass radially, thereby assisting in positioning the connector 22c-1.

[0045] The screwing head 1300 is used to rotate horizontally under the drive of the rotating mechanism 1400, so as to generate a suitable torque to lock the nut 22d at the upper end of the transducer battery cell 2. The screwing head 1300 is connected to the rotating mechanism 1400, which is located above the accommodating hole 1221, and its lower part has a socket for socketing the nut 22d.

[0046] Specifically, Fig.10 and Fig.11 As shown, the screwing head 1300 includes a sleeve 1310, a connecting piece 1320 and a bolt 1330, and the rotating mechanism 1400 is a reduction motor, which is fixed on the sliding plate 1130, and the output shaft 1410 of the reduction motor faces downward.

[0047] The sleeve 1310 is divided into a thick section 1311 and a thin section 1312 from top to bottom. The inner wall of the thick section 1311 has a sliding groove extending up and down. The outer wall of the output shaft 1410 has a key body 1411. The sleeve 1310 and the output shaft 1410 are matched through the keyway to achieve up and down sliding and transmit torque. The intersection of the inner holes of the thick section 1311 and the thin section 1312 is provided with a fixed step 1311a, and a connecting piece 1320 is fixed on the fixed step 1311a. The connecting piece 1320 is passed through by a bolt 1330 from bottom to top, and the upper end of the bolt 1330 is fixed to the output shaft 1410. A spring 1340 is sleeved on the bolt 1330. The spring 1340 is located between the connecting piece 1320 and the lower end surface of the output shaft 1410. The lower mouth of the thin section 1312 of the sleeve 1310 is the above-mentioned socket.

[0048] The lifting mechanism 1500 is used to drive the rotating mechanism 1400 to descend so that the screwing head 1300 is sleeved onto the nut 22 d . The lifting mechanism 1500 is connected to the rotating mechanism 1400 .

[0049] Specifically, the lifting mechanism 1500 uses an electric cylinder, which is fixed on the back plate 1110 .

[0050] When assembling the transducer cell, rough assembly is performed manually first: first, multiple ceramic sheets 22b and multiple conductive sheets 22c are staggered and stacked on the stud 22a, and then the nut 22d is put on the stud 22a, the ceramic sheets 22b and the conductive sheets 22c are pre-tightened, and the position of the connector 22c-1 of each connecting sheet 22c is adjusted, so that the connectors 22c-1 of adjacent connecting sheets 22c are at an angle of 180 degrees on the horizontal plane of the vertical projection, and the connectors 22c-1 and the clamping groove 21a-1 are at an angle of 90 degrees on the horizontal plane of the vertical projection.

[0051] After the rough assembly is completed, the roughly assembled battery cell is inserted into the accommodating hole 1221 of the positioning seat 1200. During the insertion process, under the limitation of the two positioning grooves 1224, the connectors 22c-1 of the adjacent conductive sheets 22c are at an angle of 180 degrees. After the insertion is completed, the transducer battery cell 2 is clamped on the left and right at a pair of symmetrical clamping grooves 21a-1 through the pin 1223 to prevent it from rotating.

[0052] The lifting mechanism 1500 drives the screwing head 1300 to descend, and the sleeve 1310 will be pushed up, so that the spring 1340 is compressed. At the same time, the rotating mechanism 1400 drives the screwing head 1300 to rotate horizontally. The socket may not be aligned with the nut 22d initially. When the screwing head 1300 rotates to the aligned position, under the resetting action of the spring 1340, the socket is connected to the nut 22d, and the nut 22d is further locked to complete the assembly of the transducer battery cell 2.

[0053] Example 2

[0054] The assembly tool provided in this embodiment is suitable for a transducer cell of another specification, such as Fig.13 and 14 As shown, the battery cell 3 of this specification is similar to the battery cell structure in Example 1, the difference is that a pair of clamps 31a are formed on the circumference of the base 31, and the battery cell body 32 has a tightening screw 32a instead of a stud, and the nut of the tightening screw 32a has a hexagonal bayonet 32b.

[0055] like Fig.12 , 15 As shown in FIG. 16 , the assembly tool of this embodiment has the same structure as that of the embodiment 1, and the difference is that:

[0056] 1. The block 1220 of the positioning seat 1200 has only a first positioning structure for restraining the transducer core 3 to prevent it from rotating.

[0057] like Fig.17 As shown, the first positioning structure includes a pair of clamping blocks 1222 corresponding to a pair of clamping openings 31a. The pair of clamping blocks 1222 are symmetrically formed on the inner wall of the accommodating hole 1221, and can just clamp the transducer core 3 at the pair of clamping openings 31a, thereby restraining the transducer core 3 to prevent it from rotating.

[0058] 2. The structure of the screwing head 1300 is different from that of the embodiment 1. Fig.18 As shown, the screwing head 1300 includes a sleeve 1310 , a slider 1320 , and a screwing rod 1330 .

[0059] The upper portion of the sleeve 1310 is fixed to a key body 1411 on the output shaft 1410 of the reduction motor, thereby transmitting torque.

[0060] The slider 1320 and the sleeve 1310 slide together up and down:

[0061] like Fig.18 and Fig.19 As shown, both sides of the left and right sides of the slider 1320 have waist-shaped grooves 1321 in the up and down directions, and the two waist-shaped grooves are symmetrical on the left and right. Two pins 1311 corresponding to the two waist-shaped grooves 1321 are horizontally fixed on the sleeve 1310 through threads. The pins 1311 pass through the sleeve and extend into the corresponding waist-shaped grooves 1321. The slider 1320 and the sleeve 1310 are slidably matched up and down through the pins 1311 and the waist-shaped grooves 1321.

[0062] like Fig.19 As shown, a spring 1340 is provided between the top of the slider 1320 and the output shaft 1410 , the lower portion of the spring 1340 is installed in the slider 1320 , and the upper portion is fixed to the bolts on the output shaft 1410 .

[0063] The slider 1320 has mounting holes in the up-and-down directions. The upper portion of the screw rod 1330 extends into the mounting holes from bottom to top and is locked by locking screws 1322 on the left and right sides of the slider 1320 to achieve fixation with the slider 1320 .

[0064] The locking screw 1322 is fixed horizontally on the slider 1320 through a thread. Fig.21 As shown, a steel ball 1322a is elastically arranged at the head by an internal spring, and a locking groove 1331 corresponding to the steel ball 1322a is formed on the upper part of the screw rod 1330, see Fig. 20 Such a structure can realize the convenient replacement of the screw rod 1330 as a consumable.

[0065] The lower end of the screw rod 1330 forms a hexagonal clamping joint for clamping into the clamping socket 32 ​​b of the nut of the tightening screw 32 a of the transducer battery core 3 .

[0066] When assembling the transducer core 3, rough assembly is first performed manually: the screws 32a are turned to pre-tighten the ceramic sheet and the conductive sheet thereon.

[0067] After the rough assembly is completed, the roughly assembled battery cell is inserted into the receiving hole 1221 of the positioning seat 1200, and the transducer battery cell 3 is clamped by the clamping block 1222 and the clamping opening 31a to prevent it from rotating.

[0068] The lifting mechanism 1500 drives the screwing head 1300 to descend, and the screwing rod 1330 will be pushed up, driving the slider 1320 to slide upward, so that the spring 1340 is compressed. At the same time, the rotating mechanism 1400 drives the screwing head 1300 to rotate horizontally. The card connector may not be aligned with the card slot of the tightening screw 32a initially. When the screwing head 1300 rotates to the aligned position, under the resetting action of the spring 1340, the card connector is inserted into the card slot 32b, thereby further locking the tightening screw 32a to complete the assembly of the transducer battery cell 3.

[0069] As can be seen from the above, the transducer cell assembly tool of the present application positions the transducer cell through a positioning seat, and provides a suitable torque for the screwing head to lock the transducer cell through a rotating mechanism, thereby improving efficiency and reducing labor costs.

[0070] Obviously, those skilled in the art should realize that the above embodiments are only used to illustrate the present invention, and are not used to limit the present invention. As long as they are within the spirit of the present invention, any changes or modifications to the above embodiments will fall within the scope of the claims of the present invention.
