[0030] A pressing device for protecting the appearance of a product from scratches, such as Figure 1 to Figure 3 As shown, it includes a base 10, a positioning seat 40 arranged on the base 10, and an upper mold pressing head 20 located above the base 10. The positioning seat 40 has a cavity 401 for inverted placement of a camera body 50 and a curved front cover 60 that are pre-positioned and coaxially sleeved together. The upper mold pressing head 20 presses down the rear portion 51 of the camera body 50 to apply force to press the camera body 50 and the curved front cover 60 together.

[0031] like Figure 1 , Figure 4 , Figure 5 As shown, the cavity 401 of the positioning seat 40 includes a tail groove 411 for the tail 51 of the camera body 50 to rest, a curved front cover 60 protection groove 421 for the curved front cover 60 to rest, and a pair of make way holes 422 for the head 52 of the camera body 50 extending out of the curved front cover 60 to make way, which are coaxially arranged in sequence from top to bottom; the positioning seat 40 includes a protective member 42 with elastic deformation ability embedded in the interior thereof, and the protective groove 421 and the make way holes 422 are both opened on the protective member 42; when the curved front cover 60 resting on the protective groove 421 is pressurized, the protective member 42 undergoes elastic deformation to absorb the pressure applied to the curved front cover 60 by the upper mold pressing head 20 through the camera body 50; thereby, non-rigid contact is formed between the curved front cover 60 and the groove wall of the protective groove 421, which effectively avoids the problem of scratches and scratches on the product surface of the curved front cover 60 that are easy to occur in the traditional pressing process, and greatly improves the yield rate of the assembled camera product.

[0032] like Figure 1 , Figure 4 , Figure 5As shown, the positioning seat 40 also includes a positioning block 41 tightly mounted on the outer periphery of the protective member 42, a tail groove 411 is opened on the upper part of the positioning block 41, and a slot 412 is opened at the lower part of the positioning seat 40, which is communicated with the tail groove 411 and is coaxially inserted into the protective member 42. An interference contact is formed between the protective member 42 and the groove wall of the slot 412, so that there is no gap between the two. With such a design, when the upper mold pressing head 20 presses down the camera body 50 and the curved front cover 60, the camera body 50 and the curved front cover 60 can be effectively prevented from being misaligned, thereby improving the assembly accuracy of the assembled camera product and further improving the yield rate of the finished product.

[0033] like Figure 1 to Figure 5 As shown, two opposite sides of the positioning block 41 are provided with pick-up and placement grooves 413 which are connected to the tail groove 411, and the groove walls on the opposite sides of the pick-up and placement grooves 413 are gradually tapered toward the direction of the tail groove 411. Such a design is not only convenient for the staff to manually load the camera body 50 and the curved front cover 60, but also convenient for the staff to remove the finished product from the cavity 401 of the positioning seat 40 with their fingers after the pressing and assembly is completed.

[0034] It should be noted here that the positioning block 41 is made of hard material, which makes the groove wall of the tail groove 411 on the positioning block 41 form a rigid contact with the tail 51 of the camera body 50, and stably positions the camera body 50 in the tail groove 411. The positioning block 41 can be made of materials with high structural strength such as polypropylene and stainless steel; and the protective member 42 in this embodiment is a product of soft elastic material. Preferably, the protective member 42 is a polyurethane product with a material close to that of the curved front cover 60, thereby more effectively absorbing the pressure applied to the curved front cover 60 by the upper mold head 20 through the camera body 50, thereby improving the yield rate of assembled cameras.

[0035] like Figure 5 As shown, the curved front cover 60 has a vertical circumferential surface 61 and a curved cover surface 62 connected along the axial direction on its circumferential side, and the protective groove 421 includes a vertical circumferential groove 4211 for covering the vertical circumferential surface 61 of the curved front cover 60 and a curved cover groove 4212 for forming a pressure contact with the curved front cover 60. Such a design can enable the protective groove 421 to stably support the curved front cover 60, thereby preventing the curved front cover 60 from moving or misaligning relative to the vertical circumferential groove 4211 or the curved cover groove 4212 during the pressing process, so as to ensure the accuracy of the pressing assembly process.

[0036] like Figure 1 and Figure 2 As shown, the base 10 is provided with an embedding groove 101 for the positioning seat 40 to be embedded in; two columns 11 are arranged on the base 10 at intervals, and a pressing cylinder 30 for driving the upper mold pressing head 20 to rise and fall is installed on the horizontal plate fixed at the top of the two columns 11, and the piston rod end of the pressing cylinder 30 is fixedly connected to the upper mold pressing head 20.

[0037] Combination Figure 1 to Figure 5 , the working principle of the utility model is described in detail below.

[0038] Before pressing, the camera body 50 and the curved front cover 60 that are pre-positioned and coaxially sleeved together are placed upside down in the cavity 401. The curved front cover 60 is supported by the protective groove 421 on the protective member 42. The pressing cylinder 30 is started, and the piston rod of the pressing cylinder 30 drives the upper mold pressing head 20 to press down the tail 51 of the camera body 50 extending out of the tail groove 411, so as to press the camera body 50 and the curved front cover 60 coaxially together. During this process, the protective member 42 undergoes elastic deformation to absorb the pressure applied by the upper mold pressing head 20 to the curved front cover 60 through the camera body 50, so as to avoid plastic deformation of the curved front cover 60 during the pressing process, which may cause the front cover to be scratched.

[0039] The above embodiments are only used to illustrate the present invention, not to limit the present invention. A person skilled in the art may make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the present invention and be defined by the claims.
