Description

Technical Field

[0001] The utility model relates to the field of photovoltaic welding strip production equipment, in particular to a tin bead blocker. Background Art

[0002] Tinned copper wire is the main raw material for the production of photovoltaic welding ribbons. During the production process, the tinned copper wire needs to undergo the process of tin plating in a tin pool. During the actual tin plating, sometimes excess tin is brought out of the tin pool by the copper wire and condensed into a sphere attached to the copper wire. Therefore, a special tin bead blocker is needed to scrape the tin beads from the copper wire. Although the commonly used tin bead blockers have good blocking effects, in actual production, there are many specifications of copper wire. Every time the specifications need to be adjusted, the tin bead blocker needs to be replaced. After replacement, the position of the tin bead blocker needs to be readjusted each time so that the copper wire can just pass through the wire groove of the tin bead blocker, which is more troublesome. Utility Model Content

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0019] See also Figures 1 to 3 , the utility model embodiment includes:

[0020] A tin bead blocker, the tin bead blocker comprising: a blocker body 1 and an L-shaped bracket 2, the blocker body 1 is a regular octagonal structure, a wire slot 101 is vertically opened in the middle of each side, the gap widths of different wire slots 101 correspond to the diameters of tinned copper wires of different specifications, the specifications of the eight wire slots 101 arranged on the eight sides are 0.22mm, 0.24mm, 0.27mm, 0.28mm, 0.3mm, 0.31mm, 0.32mm, 0.35mm, respectively, the opening depth of all the wire slots 101 is between 1 and 3cm, and the actual depth is generally 2.5cm, an upper positioning shaft hole 103 is provided in the middle position of the blocker body 1, a positioning pin hole 104 is provided between each wire slot 101 and the upper positioning shaft hole 103, and each positioning pin hole 104 is at the same distance from the center of the upper positioning shaft hole 103;

[0021] The L-shaped bracket 2 includes a blocker positioning plate 201 and a mounting seat 202 which are perpendicular to each other, and the mounting seat 202 is provided with three threaded connection holes 205. A lower positioning shaft hole 203 is provided in the middle position of the end of the blocker positioning plate 201, and the lower positioning shaft hole 203 corresponds to the position of the upper positioning shaft hole 103. The blocker positioning plate 201 is also provided with a positioning slot 204 that matches the position of the positioning pin hole 104. When the tin bead blocker is installed, the upper positioning shaft hole 103 and the lower positioning shaft hole 203 are connected by a rotating shaft, and the positioning pin hole 104 and the positioning slot 204 are connected by a pin. After the connection is completed, the opening of a wire groove 101 is located exactly on the movement path of the tinned copper wire in front.

[0022] There are three lower positioning shaft holes 203, and the centers of all lower positioning shaft holes 203 are on a straight line. In this way, the installation position of the blocker body 1 can be adjusted according to the position of the tinned copper wire during actual installation, so that the tinned copper wire can just pass through the middle position of the wire groove 101. The positioning slot 204 is a long waist slot. Since there are three lower positioning shaft holes, in order to facilitate installation and positioning, the positioning slots 204 are all opened as long waist holes, which can meet the positioning needs of three positions at the same time. There are two positioning slots 204, which are symmetrically arranged on the blocker positioning plate 201. In this way, both sides are positioned at the same time during positioning, which can improve the stability of the installation of the blocker body 1.

[0023] The threaded connection hole 205 on the mounting seat 202 is a horizontal long waist hole, so when the mounting seat 202 is fixed with bolts, the position can be fine-tuned within the range of the horizontal long waist hole so that the tinned copper wire can be just stuck in the wire groove 101.

[0024] Each side of the blocker body 1 is provided with a wire-receiving groove 102, and all the wire-receiving grooves 102 are arranged on the same side of the corresponding wire-passing groove 101. In this way, the copper wire to be processed can be temporarily placed in the wire-receiving groove 102 when the blocker body 1 is adjusted.

[0025] When the utility model is actually used, the tinned copper wire is put into the wire groove 101, and the wire groove 101 is used to scrape off the excess tin beads carried by the copper wire from the tin pool. When the specification of the copper wire needs to be changed, it is only necessary to pull out the pins inserted in the positioning pin hole 104 and the positioning slot 204, and then rotate the tin bead blocker body 1, align the notch of the wire groove 101 of the corresponding specification to the front, and then insert the pin into the upper positioning pin hole 204 aligned with the positioning slot 204, so as to fix the tin bead blocker body 1. During the adjustment process, the copper wire can be temporarily placed in the wire storage groove 102 to prevent interference with manual adjustment by on-site personnel. After the adjustment is completed, the tinned copper wire is placed in the adjusted wire groove 101.

[0026] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
