Example 1

In order to solve the technical problems of complex disassembly and assembly and high maintenance cost of the conventional comb plate, embodiment 1 provides a comb plate 01 for bearing battery pieces, as shown in fig. 1, comprising a base plate 1 and a plurality of comb teeth 2; the comb teeth 2 are detachably arranged on the base plate 1; all the comb teeth 2 are arranged in a row on the base plate 1. The comb plate 01 for bearing the battery pieces provided by the embodiment 1 is designed to be a detachable combined structure of a base plate 1 and a plurality of comb teeth 2. When meetting individual broach 2 and taking place the fracture phenomenon, only need to dismantle alone (dismantle from base plate 1 with cracked broach 2) 2 that takes place fracture, then install new broach 2 on base plate 1 can, need not to dismantle whole broach plate from automatic picture peg machine. Compared with the traditional comb plate, the comb 2 is more convenient to assemble, disassemble and replace; compare with changing whole fishback, only change 2 maintenance cost greatly reduced of broach of individuality damage.

The detachable structure between the comb teeth 2 and the base plate 1 includes, but is not limited to, plugging and screwing, and preferably, the comb teeth 2 and the base plate 1 are screwed. Through threaded connection, firstly, ensured the joint strength between broach 2 and the bed plate 1 for broach 2 is difficult to deviate from for bed plate 1, secondly made things convenient for the maintenance of later stage broach 2 to change, through twisting broach 2, can dismantle and install broach 2 at any time.

In order to minimize the damage of the comb plate to the surface of the battery piece, further, as shown in fig. 2, the comb teeth 2 include a first portion 20 and a second portion 21; the first portion 20 is formed integrally with the second portion 21; the first portion 20 is cylindrical; the second portion 21 is conical; one of the bottom surfaces of the cylindrical body 20 completely coincides with the bottom surface of the conical body 21, and the other bottom surface of the cylindrical body 20 is detachably fixed to the base plate 1. Because broach 2 comprises cylindric 20 and circular cone 21, and the face that contacts with the battery piece on broach 2 is cylindrical curved surface, and what form with platelike battery piece is line contact, and not face contact, through the shape design of above-mentioned unique broach 2, can be with the area of contact greatly reduced of broach 2 and battery piece to the damage of at utmost reduction broach board 01 to the battery piece surface. The structure of the conical body 21 can provide enough insertion space for the battery plate, thereby facilitating the quick insertion and installation of the battery plate. Through practical test, the comb teeth 2 adopting the structure can improve the yield of photovoltaic cell products by 0.1%. And in subsequent use, can change the broach 2 of damage alone, it is very convenient to maintain, can effectively reduce cost of maintenance.

In order to reduce the damage caused by the relative movement of the battery piece and the surface of the comb teeth as much as possible during the process of inserting the battery piece into the gap between the comb teeth, further, as shown in fig. 2, the vertex of the cone 21 is transited by a spherical arc surface 210; the junction of the first portion 20 and the second portion 21 is transited by a rounded chamfer 22. The conical top of the spherical cambered surface 210 and the arc chamfer 22 are arranged, so that burrs generated in the machining process of the comb teeth 2 are greatly reduced, the machining precision is ensured, and the damage caused by the relative motion of the cell piece and the surface of the comb teeth is reduced as much as possible.

In order to facilitate the detachable installation of the comb teeth and the base plate, further, as shown in fig. 3, one surface of the base plate 1 is provided with a plurality of first installation holes 10 for installing the comb teeth 2; all the first mounting holes 10 are arranged in a row at equal intervals; the first mounting holes 10 are provided in one-to-one correspondence with the comb teeth 2 (see fig. 1). The detachable plug-in mounting of the comb teeth 2 and the base plate 1 can be facilitated by arranging a plurality of first mounting holes 10 arranged in a row on the base plate 1. The grafting cooperation between first mounting hole 10 and the broach 2, the effective area of contact between the two increases to increased the fixed strength of broach 2, reduced droing of broach 2.

In order to conform to the cylindrical shape of the comb teeth, specifically, as shown in fig. 3, the first mounting hole 10 is a circular blind hole; the cylindrical shape 20 of the comb teeth 2 is adapted to the circular blind hole 10 (see fig. 1). Through setting up circular blind hole 10, can with 20 shape looks adaptations of cylinder, increase the effective area of contact between bed plate 1 and the broach 2, improve the firm degree of fixation of broach 2 on bed plate 1.

In the actual use process, the comb teeth are usually broken along the root, so that residual roots which are difficult to be separated can be generated in the first mounting holes of the base plate, and the replacement of the comb teeth is difficult. In order to solve the problem, as shown in fig. 3, a plurality of tooth-withdrawing holes 11 are further formed in one surface of the base plate 1 adjacent to the surface where the first mounting hole 10 is located; the tooth-removing holes 11 are arranged in one-to-one correspondence with the first mounting holes 10; the extending direction of the tooth retreating hole 11 is perpendicular to the extending direction of the first mounting hole 10, and the tooth retreating hole 11 is communicated with the first mounting hole 10. Move back the perforation 11 through the setting, when the incomplete root of broach 2 appeared and is stayed in first mounting hole and be difficult to deviate from, can be less than the stereoplasm shaft-like thing of moving back perforation 11 with the help of the diameter, stretch into first mounting hole 10 with the stereoplasm shaft-like thing by the outside of bed plate 1 along moving back perforation 11, through dialling the incomplete root of broach 2 from top to bottom, help the incomplete root breaks away from in first mounting hole 10, the incomplete root of having solved broach 2 is left over, the broach 2 that causes changes the problem of difficulty.

In order to facilitate the installation and fixation of the comb plate and the sheet inserting machine, further, as shown in fig. 3 and 4, a plurality of second installation holes 12 are further formed in the base plate 1; the second mounting hole 12 is used for fixing with a sheet inserting machine. The second mounting hole 12 may be a threaded hole. Simple and convenient installation and fixation of the comb plate 01 and the sheet inserting machine can be realized through the second installation holes 12.

In order to prolong the service life of the base plate, the base plate 1 is further made of PEEK. PEEK (polyetheretherketone) is a special engineering plastic with excellent properties of high temperature resistance, self-lubrication, easy processing and high mechanical strength, which has: 1. corrosion resistance and ageing resistance; 2. resistance to dissolution; 3. the method is suitable for high-temperature, high-frequency and high-voltage electrical property conditions; 4. the toughness and the rigidity are both good; 5. wear resistance; 6. antistatic and good electrical insulation performance; 6. low smoke and toxic gas emission. The base plate 1 made of PEEK has the advantages, is particularly suitable for bearing the battery piece, and has longer service life and lower cost compared with a base plate made of ceramic materials.

In order to further reduce the damage of the comb teeth on the surface of the cell, the comb teeth 2 are preferably made of ceramic. The ceramic material has high surface finish, the friction coefficient between the comb teeth 2 made of ceramic and the battery piece is small, and the damage of the comb teeth to the surface of the battery piece can be reduced.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structural changes made by the contents of the specification and the drawings, or the direct or indirect application in other related technical fields, are included in the same way in the protection scope of the present invention.
