Detailed Description

In order to facilitate understanding of the present invention, the present invention will be described more fully hereinafter with reference to the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. The invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete.

As shown in fig. 1-4, a liquid recovery box comprises a box body 1 and a guide plate 2, wherein the guide plate 2 is arranged at the right end of the box body 1, the guide plate 2 is obliquely arranged to form an oblique opening, and a gap 3 is formed between the guide plate 2 and the box body 1.

The box body 1 consists of a side wall 11, a box bottom 12 and a recovery pipeline 13, the bottom end of the side wall 11 is connected with the box bottom 12 to form a cavity, and the recovery pipeline 13 is connected with one side of the box bottom 12 far away from the cavity. The sidewall 11 is vertically disposed, the sidewall 11 is divided into a first sidewall 111, a second sidewall 112 and a third sidewall 113, the two second sidewalls 112 are parallel to each other, the left end of the second sidewall 112 is connected to the third sidewall 113, and the right end is connected to the first sidewall 111. As shown in fig. 2 to 4, the first side wall 111 and the third side wall 113 are parallel and have the same length in the direction of the parallel plane, the distance between the two second side walls 112 is the same as the length of the first side wall 111, and the second side wall 112 is perpendicular to the first side wall 111, that is, the first side wall 111, the second side wall 112 and the third side wall 113 are connected to form a rectangular parallelepiped space.

The first side wall 111 is at the right end of the box body 1, i.e. at one end of the inclined opening, in the box body 1, the second side wall 112 is at the same height as the third side wall 113, while the first side wall 111 is at a smaller height than the second side wall 112, and the baffle 2 is above the first side wall 111. The length of the guide plate 2 is the same as that of the first side wall 111, the top end of the guide plate 2 and the top end of the box body 1 are in the same plane, the bottom end of the guide plate 2 is a free end, the front end and the rear end of the guide plate 2 are connected with the second side wall 112, and the guide plate 2 is perpendicular to the second side wall 112. Because guide plate 2 slope sets up, has increased the remaining liquid scope of syringe needle is received to the liquid recovery box for originally, drip the remaining liquid at liquid recovery box edge and flow to the cavity along guide plate 2 on the up end of guide plate 2, the remaining liquid of syringe needle has been avoided dripping on product or battery notes liquid equipment. The top of guide plate 2 and the top of box body 1 are in the coplanar can reduce the space that the liquid recovery box took in battery notes liquid equipment, avoid liquid recovery box and battery to annotate other parts in the liquid equipment and take place to interfere, ensure that every part normally operates.

If the inclination of the guide plate 2 is too large, the whole volume of the liquid recovery box is increased, namely the space occupied by the liquid recovery box in the battery liquid injection equipment is increased; and the too small gradient of the guide plate 2 can cause the residual liquid of the injection needle head dropping on the edge of the guide plate 2 to directly drop on a product or battery liquid injection device instead of flowing back into the cavity along the lower end surface of the guide plate 2. The inclination of the baffle 2 can be adjusted according to the actual need. In this embodiment, the angle formed by the baffle 2 and the plane on which the top of the box 1 is located is 42 °. There is clearance 3 between guide plate 2 and the first side wall 111, and clearance 3's setting is in order to make the injection needle residual liquid that drips on guide plate 2 get back to box body 1 in, lets the dropping liquid directly get back to in the box body 1, and the recycle line 13 of 12 at the bottom of the box of process discharges again, need not artificial interference. The length of the gap 3 is the same as that of the guide plate 2, thus ensuring that the residual liquid of the injection needle dropping on the edge of the guide plate 2 can flow back into the box body 1 along the lower end surface of the guide plate 2.

The box bottom 12 is composed of four inclined plates, the top ends of the inclined plates are connected with the bottom ends of the side walls 11, the bottom ends of the inclined plates are connected with the top end of the recovery pipeline 13, and the inclined design of the box bottom 12 is beneficial to liquid in the cavity to be collected to the recovery pipeline 13 and to be discharged through the recovery pipeline 13.

The utility model has the advantages of it is following: 1. the guide plate which is obliquely arranged is arranged, so that the area of the liquid recovery box for receiving the residual liquid of the injection needle is increased, the residual liquid which originally drips on the edge of the liquid recovery box drips on the upper end surface of the guide plate 2 and flows into the cavity along the guide plate 2, and the residual liquid of the injection needle is prevented from dripping on a product or a battery liquid injection device; 2. the inclination of the guide plate is regulated, so that the volume of the liquid recovery box is ensured as much as possible while the residual liquid of the injection needle can flow back to the box body along the guide plate, and the interference of the liquid recovery box with other parts in the battery liquid injection equipment due to the overlarge volume is avoided; 3. a gap is formed between the guide plate and the box body, so that residual liquid of the injection needle dropped on the guide plate directly flows back into the box body and is discharged through a recovery pipeline, manual interference is not needed, and extra labor cost is avoided. The utility model discloses can reduce the dropping liquid effectively and to the corruption of product or battery notes liquid equipment, improve the product goodness, reduce total manufacturing cost.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is more specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
