[0029] Due to its small size, linear motors are widely used in consumer electronic products such as mobile phones and tablets, using vibration to replace the notification sound. Among them, the linear motor is formed by welding multiple metal sheet parts. How to accurately assemble each metal sheet part has become a key issue determining the function and quality of the linear motor. In the prior art, during the manufacturing process of the linear motor, when welding multiple metal thin parts, manual clamping is usually used to achieve the guiding and positioning of the metal sheet parts, with low efficiency, low precision, and low yield of the product. To solve the above defects in the prior art, this application is proposed. The following are specific embodiments of this application.

[0030] Figure 1 For the structural schematic diagram of the positioning mechanism 100 provided by the present invention, please refer to Figure 1 , an embodiment of the present invention provides a positioning mechanism 100, including: a first driving mechanism 110, a second driving mechanism 120, and a guiding and positioning plate 130. The driving direction of the first driving mechanism 110 is perpendicular to the driving direction of the second driving mechanism 120. The guiding and positioning plate 130 is fixedly arranged at the driving end of the second driving mechanism 120. The second driving mechanism 120 is arranged at the driving end of the first driving mechanism 110. A positioning through hole 131 is provided on the guiding and positioning plate 130. The opening direction of the positioning through hole 131 is perpendicular to the plate surface direction of the guiding and positioning plate 130, and is used to position the metal sheet to be welded through the positioning through hole 131.

[0031] It should be noted that, first, the positioning mechanism 100 in this embodiment is applicable to the welding process of thin metal sheets. For example, the metal sheets that make up a linear motor. The working principle of a linear motor is to convert electrical energy into mechanical energy, driving a spring mass block to perform linear motion, thereby generating vibration. Linear motors can be further divided into horizontal linear motors and vertical linear motors. A vertical linear motor can only vibrate along the Z-axis, with a relatively short vibration stroke, weak vibration force, and short vibration duration. While a horizontal linear motor can vibrate along the X and Y axes, with a longer vibration stroke, fast startup speed, controllable vibration direction, and is more compact in structure, which is more conducive to reducing the thickness of the mobile phone body.

[0032] Second, in this embodiment, the metal sheet to be welded in the positioning through-hole 131 is a small metal sheet, and the metal sheet to be welded in the clamping mechanism is a large metal sheet. The following embodiments will describe the two metal sheets to be welded as large metal sheets and small metal sheets respectively.

[0033] Third, the positioning mechanism 100 in this embodiment is used to position the small metal sheet. The large metal sheet is fixed and positioned through the clamping mechanism. The first driving mechanism 110 drives the guiding and positioning plate 130 to reciprocate between the processing position and the non-processing position of the thin metal sheet part. The second driving mechanism 120 drives the guiding and positioning plate 130 to approach or move away from the large metal sheet. The guiding and positioning plate 130 is used to position the small metal sheet, so that the small metal sheet can be accurately and efficiently welded and fixed on the large metal sheet.

[0034] Exemplarily, please refer to Figure 2 , Figure 2 which is the initial state of the positioning mechanism 100, that is, the initial states of the first driving mechanism 110 and the second driving mechanism 120. The driving cylinder 111 in the first driving mechanism 110 drives the second driving mechanism 120 to drive the guiding and positioning plate 130 to extend. Please refer to Figure 3 , Figure 3This is the state where the positioning mechanism 100 extends under the driving force of the first driving mechanism 110. The driving cylinder 111 drives the guiding and positioning plate 130 to the processing position of the metal sheet part. At the same time, the second driving mechanism 120 drives the guiding and positioning plate 130 to move downward, that is, move closer to the large metal sheet until the lower bottom surface of the guiding and positioning plate 130 abuts against the upper surface of the large metal sheet. A small metal sheet is placed in the positioning through-hole 131 on the guiding and positioning plate 130. The positioning through-hole 131 can position the small metal sheet. Finally, the positioned large metal sheet and small metal sheet are welded until the welding of the large metal sheet and small metal sheet is completed. When the welding of the large metal sheet and small metal sheet is completed, first, the second driving mechanism 120 drives the guiding and positioning plate 130 away from the small metal sheet. When the guiding and positioning plate 130 leaves the small metal sheet, the driving end of the driving cylinder 111 retracts to the initial state. In this way, the positioning of the small metal sheet before welding is completed without manual intervention, with high efficiency. Since the driving distance of the driving mechanism is fixed, the probability of error is small, thereby improving the yield of the product.

[0035] A positioning mechanism 100 provided by an embodiment of the present invention is composed of a first driving mechanism 110, a second driving mechanism 120, and a guiding and positioning plate 130. Specifically, the driving direction of the first driving mechanism 110 is perpendicular to the driving direction of the second driving mechanism 120 to achieve the driving of the positioning mechanism 100 in two perpendicular directions. The guiding and positioning plate 130 is fixedly arranged at the driving end of the second driving mechanism 120 to achieve the driving of the guiding and positioning plate 130 by the second driving mechanism 120 along the driving direction of the second driving mechanism 120. The second driving mechanism 120 is arranged at the driving end of the first driving mechanism 110 to achieve the driving of the second driving mechanism 120 by the first driving mechanism 110 along the driving direction of the first driving mechanism 110. Through the driving of the above first driving mechanism 110 and second driving mechanism 120, the guiding and positioning plate 130 reciprocates between the processing position and the non-processing position of the metal sheet part. A positioning through-hole 131 is provided on the guiding and positioning plate 130. The opening direction of the positioning through-hole 131 is perpendicular to the plate surface direction of the guiding and positioning plate 130 and is used to position the metal sheet to be welded through the positioning through-hole 131. The metal sheet to be welded can be accurately positioned through the positioning through-hole 131 to improve the welding efficiency and accuracy.

[0036] Figure 4 For the schematic cross-sectional view of the positioning through-hole 131 provided by an embodiment of the present invention, please refer to Figure 4 Furthermore, the side wall of the longitudinal section of the positioning through-hole 131 in this embodiment includes an auxiliary section 1311 and a positioning section 1312 that are connected to each other. The width of the auxiliary section 1311 of the positioning through-hole 131 is greater than the width of the positioning section 1312 of the positioning through-hole 131.

[0037] It should be noted that the side wall of the longitudinal section of the positioning through hole 131 is configured to be two interconnected parts, namely the auxiliary section 1311 and the positioning section 1312, and the connection between the auxiliary section 1311 and the positioning section 1312 is smooth and not bent. If there is a bend, the auxiliary section 1311 will not guide the small metal sheet clearly, and the small metal sheet needs to be positioned again when entering the positioning section 1312, which complicates the entire guiding and positioning process. Therefore, the connection between the auxiliary section 1311 and the positioning section 1312 is configured to be smooth. Among them, the auxiliary section 1311 is used to guide the small metal sheet so that the small metal sheet can accurately enter the positioning section 1312, and the positioning section 1312 is used to position the small metal sheet, avoiding manual intervention and improving the welding efficiency of metal sheet parts. If the side wall of the longitudinal section of the positioning through hole 131 only has the auxiliary section 1311 , the small metal sheet is prone to side sliding or one side lifting when the small metal sheet is processed. Therefore, the positioning section 1312 needs to be provided.

[0038] For example, the positioning through hole 131 is a rectangular hole, or the positioning through hole 131 is a circular hole.

[0039] It should be noted that the size of the positioning through hole 131 is not limited here. For example, if the area of the small metal sheet is large, the corresponding cross-sectional area of the positioning through hole 131 is large. Conversely, if the area of the small metal sheet is small, the cross-sectional area of the positioning through hole 131 is small. In other words, the size of the cross-sectional area of the positioning through hole 131 corresponds to the area of the small metal sheet. The shape of the positioning through hole 131 can be a circular hole or a rectangular hole. When the part of the small metal sheet that needs to be limited forms a rectangle, the corresponding positioning through hole 131 can be set in a rectangular shape. When the shape of the part of the metal sheet that needs to be limited is irregular, the positioning through hole 131 can be set in a circular shape. Those skilled in the art can make corresponding choices according to actual needs. In addition, the shape of the positioning through hole 131 is not limited to the rectangular hole and circular hole given above, and can also be a positioning hole of other shapes, as long as it can achieve the guidance and positioning of the small metal sheet.

[0040] Optionally, when the positioning through hole 131 is a circular hole, a plurality of limiting grooves are provided in the positioning section 1312 of the circular hole.

[0041] When the positioning through hole 131 is a circular hole, the small metal sheet is easy to rotate when positioning the small metal sheet, thereby affecting the welding accuracy of the small metal sheet. Therefore, when the positioning through hole 131 is a circular hole, in order not to affect the welding accuracy of the small metal sheet, it is necessary to set a plurality of limiting grooves in the positioning section 1312 of the circular hole to limit the small metal sheet and prevent it from rotating in the positioning through hole 131.

[0042] In the above scheme of this embodiment, the second driving mechanism 120 drives the guide positioning plate 130 to move. Here, a specific feasible implementation scheme is given. The positioning mechanism 100 also includes a guide mechanism, and the second driving mechanism 120 drives the guide positioning plate 130 to move on the guide mechanism.

[0043] The guiding direction of the guiding mechanism is the same as the driving direction of the second driving mechanism 120 , and the entire structure of the second driving mechanism 120 can move on the guiding mechanism.

[0044] The above solution provides a guiding mechanism. Specifically, the guiding mechanism includes a guiding rail 151 and a guiding slider 152 arranged in the guiding rail 151 . The guiding slider 152 is connected to the guiding positioning plate 130 .

[0045] The extending direction of the guide rail 151 is the same as the driving direction of the second driving mechanism 120 .

[0046] By way of example, the present embodiment also includes a fixed plate, which has an L-shaped structure. The L-shaped fixed plate includes a horizontal plate and a vertical plate that are connected to each other, wherein the cylinder body of the driving cylinder 111 is arranged below the horizontal plate, and a guide rail 151 and a second driving mechanism 120 are arranged on the side of the vertical plate away from the driving cylinder 111. The driving end of the second driving mechanism 120 is connected to the guide slider 152 to drive the guide slider 152 to move in the guide slider 151, and the guide slider 152 is connected to the guide positioning plate 130 so that when the second driving mechanism 120 drives the guide slider 152, it drives the guide positioning plate 130 to move.

[0047] Optionally, the positioning mechanism 100 in this embodiment further includes a hanging connecting plate 140 , the guide slider 152 is connected to the guide positioning plate 130 via the hanging connecting plate 140 , and the hanging connecting plate 140 is parallel to the guide positioning plate 130 .

[0048] It should be noted that the suspension connecting plate 140 is fixedly connected to the guide slider 152 , and the suspension connecting plate 140 is connected to the guide positioning plate 130 , and the guide positioning plate 130 can move relative to the guide positioning plate 130 to achieve a floating installation of the guide positioning plate 130 .

[0049] For example, the guide positioning plate 130 is driven by the second driving mechanism 120 to move toward the large metal sheet and abut against the large metal sheet. In order to prevent the guide positioning plate 130 from causing indentations or scratches to the large metal sheet, the guide positioning plate 130 is configured to be movable relative to the suspension connecting plate 140. When the guide positioning plate 130 abuts against the large metal sheet, if the suspension connecting plate continues to move closer to the large metal sheet, the guide positioning plate 130 will not continue to move toward the large metal sheet with the suspension connecting plate 140, thereby effectively protecting the large metal sheet from damage.

[0050] Optionally, in order to further define the structure of the suspension connecting plate 140, an implementable solution for the suspension connecting plate 140 is given here. Specifically, the suspension connecting plate 140 includes a connecting portion, and suspension portions respectively extending from opposite ends of the connecting portion. The two suspension portions are respectively connected to two ends of the guiding and positioning plate 130.

[0051] It should be noted that the connecting portion of the suspension connecting plate 140 is fixedly connected to the guiding slider 152. The two oppositely arranged suspension portions of the suspension connecting plate 140 are used to connect to the guiding and positioning plate 130. The positioning through hole 131 is located between the two oppositely arranged suspension portions, and the projections of the connecting portion and the two suspension portions do not cover the positioning through hole 131. That is to say, the projections of the connecting portion and the two suspension portions are located outside the positioning through hole 131, which is convenient for placing and welding the small metal sheet.

[0052] Among them, the structure of the suspension connecting plate 140 is not limited to the above solution, and it can also be other structures, such as a U-shaped structure or a square frame structure, as long as the projection of the suspension connecting plate 140 does not cover the positioning through hole 131.

[0053] Furthermore, in order to realize the relative movement of the guiding and positioning plate 130 relative to the suspension connecting plate 140, an implementable solution is given here. Specifically, the suspension portion in this embodiment is connected to the guiding and positioning plate 130 through an elastic member 142.

[0054] It should be noted that the number of elastic members 142 can be two, or four, or six. The elastic members 142 are respectively arranged at two ends of the guiding and positioning plate 130 to enable the guiding and positioning plate 130 to be floatingly installed relative to the suspension connecting plate 140 to protect the large metal sheet.

[0055] If two elastic members 142 are provided, the two elastic members 142 are respectively arranged at the middle positions of two ends of the guiding and positioning plate 130 to prevent the guiding and positioning plate 130 from tilting. If four elastic members 142 are provided, the four elastic members 142 are grouped in pairs, and each group of elastic members 142 is respectively arranged on both sides of two ends of the guiding and positioning plate 130 to make the guiding and positioning plate 130 balanced.

[0056] Furthermore, in order to prevent the guiding and positioning plate 130 from shaking or moving laterally, thereby affecting the positioning effect of the guiding and positioning plate 130 on the small metal sheet, a first guiding column 141 is further provided between the suspension portion and the guiding and positioning plate 130 in this embodiment. The first guiding column 141 is inserted into the elastic member 142, or, when there are multiple elastic members 142, the first guiding column 141 is located between adjacent elastic members 142.

[0057] It should be noted that the first guiding column 141 can be arranged in various ways. For example, one end of the first guiding column 141 is slidably connected to the suspension connecting plate 140, and the other end is fixedly connected to the guiding and positioning plate 130; alternatively, one end of the first guiding column 141 is fixedly connected to the suspension connecting plate 140, and the other end is slidably connected to the guiding and positioning plate 130. The first guiding column 141 can be inserted into the elastic member 142 or located outside the elastic member 142. Those skilled in the art can specifically select the arrangement mode of the first guiding column 141 according to actual needs, as long as it can guide the relative positions of the suspension connecting plate 140 and the guiding and positioning plate 130.

[0058] An embodiment of the present invention provides a processing device, including a clamping mechanism and the above-mentioned positioning mechanism 100. The clamping mechanism is used to position the large metal sheet, and the positioning mechanism 100 is used to guide and position the small metal sheet to improve the welding accuracy and accuracy of the large metal sheet and the small metal sheet.

[0059] The processing device provided by the embodiment of the present invention adopts the above-mentioned positioning mechanism 100. By arranging the positioning mechanism 100 in the processing device, the processing efficiency and product yield of the welding object can be effectively improved, that is, the processing efficiency and product yield of the welding of the large metal sheet and the small metal sheet.

[0060] Please refer to Figure 5 , optionally, in order to further guide the guiding and positioning plate 130, guiding holes 132 are respectively arranged at both ends of the guiding and positioning plate 130 in the positioning mechanism 100 of this embodiment, and second guiding columns corresponding to the guiding holes 132 are arranged on the clamping mechanism.

[0061] It should be noted that the diameter of the opening of the guiding hole 132 facing the clamping mechanism is larger than the diameter of the opening facing away from the clamping mechanism. During the driving process of the second guiding mechanism, the opening of the guiding hole 132 facing the clamping mechanism first corresponds and cooperates with the second guiding column. Therefore, the different diameters of the guiding hole 132 can effectively improve the assembly effect of the second guiding column and the guiding hole 132, and further improve the guiding effect of the second guiding column on the guiding and positioning plate 130.

[0062] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
