Description

TECHNICAL FIELD

[0001] The utility model relates to the processing technology of the car interior metal loudspeaker mesh enclosure part, specifically is a kind of plate chain structure for conveying metal appearance parts. BACKGROUND

[0002] Metal appearance part is to avoid appearance surface scratch, scratch in transfer and stamping process, usually a layer of protective film is covered on its surface, and the protective film is removed before washing, passivation and other surface treatments after single-part forming.Currently, there are two removal processes:

[0003] 1. Manual removal: manually lift the edge of the protective film with a rubber stick, and then manually tear off the protective film.

[0004] 2. Mechanical film tearing: use a flat-line film tearing device, the protective film separates from the surface of the part after passing through the film remover and ultrasonic vibration, achieving the effect of film removal.

[0005] Due to the low efficiency of manual film tearing and high labor cost, manufacturers usually choose to purchase film tearing equipment and use a flow line to tear the film. However, this solution may encounter some problems in actual production, such as: 1. If a traditional spiral mesh belt is used, the mounting feet of the metal parts may be stuck in the mesh chain holes, causing deformation and being difficult to remove; 2. The punched plate product may slide or flip during conveying, spraying, and air cutting, causing damage to the appearance of the part. UTILITY MODEL CONTENTS

[0014] Compared with the prior art, the present application has the following advantages or beneficial effects:

[0015] The conventional conveying line adopts a spiral mesh belt, which is not suitable for the transportation of metal loudspeaker mesh cover parts due to the large mesh holes. The present application uses a plate chain conveying belt, and a semi-etching groove is formed in the mesh hole (processing area) of the conveying belt. The groove penetrates the plate chain piece to form a plurality of through holes, which can meet the purpose of film tearing, cleaning, medicine spraying and exchange flow. The two sides of the plate chain piece are provided with round convex plates, and the adjacent round convex plates form a recess. When the plate chain piece is connected, the round convex plate is clamped in the recess. This structure can reduce the gap between the plate chain pieces and the pieces, and the designed gap value is less than 0.5 mm, which can avoid the problems of metal part bending foot jamming and deformation. The mesh hole (processing area) is arranged in an array, and the depth of the semi-etching groove is less than the thickness of the plate chain piece. In combination with the design of the round convex plates on both sides, the possibility of sliding or overturning of the parts during transportation can be reduced, and the appearance qualification rate of the parts can be improved.

[0022] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. Therefore, the detailed description of the embodiments of the present utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to illustrate selected embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without inventive effort are within the protection scope of the present utility model.

[0023] like Figures 1-4 As shown, this embodiment provides a plate chain conveyor belt for transporting metal parts, including plate chain segments 1 driven by sprockets. Multiple plate chain segments 1 are pivotally connected to each other. Three round protrusions 11 are spaced apart on both sides of each plate chain segment 1. A recess 12 is formed between adjacent round protrusions 11 to accommodate the round protrusions 11. When the plate chain segments 1 are connected, the round protrusions 11 are engaged in the recesses 12. This structure can reduce the gap between the plate chain segments, and the designed gap between the recesses 12 and the round protrusions 11 is <0.5mm, which can avoid the problems of metal parts getting stuck and deformed when bending. The plate chain segments 1 are provided with multiple processing areas 13 arranged in an array. Multiple grooves 131 are spaced apart in the processing areas 13. The grooves 131 penetrate the plate chain segments 1 to form elongated through holes, which can meet the purpose of spraying and exchanging the film-peeling cleaning solution. The length L of the chain link 1 is 64mm, and the thickness m is 2mm. The groove 131 is formed by semi-etching, with a length a of 5mm, a width b of 3.8mm, and a depth c of 1mm. An isolation strip 132 with a width d of 2mm is provided between adjacent grooves 131. In this structure, the depth of the groove 131 is half the thickness of the chain link 1, thus forming a concave fixing part. Multiple processing areas 13 are combined to form an array of fixing areas. Combined with the round protruding plates 11 on both sides of the chain link 1, the metal parts can be limited, reducing the possibility of slippage or overturning during transportation and improving the appearance qualification rate of the parts. Furthermore, the groove's size design ensures that the bending feet of the metal parts will not get stuck in the groove.

[0024] To further explain, the circular convex plate 11 has a mounting hole 111 inside, through which a pin passes, and both ends are fitted with connecting plugs, and are connected with the chain gear to form a complete plate chain conveyor belt.

[0025] The above merely describes preferred embodiments of the present application, and is not intended to limit the patent scope of the present application, and any equivalent structural transformation or direct or indirect application in other related technical fields based on the content of the present application specification and drawings are also included in the patent protection scope of the present application.
