The embodiments described below are examples for explaining the present application and are not intended to limit the present application.

[0022] Please refer to Figure 1 and Figure 2The embodiment of the present application provides a compression jig 100 for compressing a workpiece 200 and auxiliary material 300 attached to the workpiece 200, the workpiece 200 can be a back shell, a middle frame, a glass panel or the like of an electronic product, the electronic product can be a mobile phone, a tablet computer or the like, the auxiliary material 300 can be a small piece that needs to be attached to the workpiece 200, the auxiliary material 300 can be provided with one, two or more, the auxiliary material 300 can have a sticking surface itself, or glue or the like is coated between the workpiece 200 and the auxiliary material 300. The workpiece 200 can also be provided with a clamping groove (not shown in the figure) corresponding to the auxiliary material 300, and the auxiliary material 300 can be connected to the workpiece 200 in a clamping manner. In the embodiment, the auxiliary material 300 is installed on the workpiece 200 before the workpiece 200 and the auxiliary material 300 are compressed, and the compression jig 100 provided by the present application is used to compress the workpiece 200 and the auxiliary material 300. The compression jig 100 comprises a positioning mechanism 10 and a compression mechanism 20.

[0023] Specifically, the positioning mechanism 10 is used for positioning the workpiece 200, and when the workpiece 200 is placed on the positioning mechanism 10, the auxiliary material 300 is located on the side of the workpiece 200 away from the positioning mechanism 10.

[0024] The compression mechanism 20 comprises a cover plate assembly 21 and a plurality of compression head assemblies 22, the cover plate assembly 21 is matched with the positioning structure, a plurality of containing holes 211 are formed in the side of the cover plate assembly 21 facing the positioning mechanism 10, each compression head assembly 22 is correspondingly arranged in one containing hole 211, each compression head assembly 22 comprises a sliding piece 221 slidingly arranged in the containing hole 211 and a flexible compression head 222 connected to the sliding piece 221, and each flexible compression head 222 corresponds to each auxiliary material 300.

[0025] When the compression mechanism 20 and the positioning mechanism 10 are matched, the flexible compression head 222 abuts against the auxiliary material 300 on the workpiece 200, so as to compress the auxiliary material 300 and the workpiece 200.

[0026] In the embodiment, the cross-sectional area of one end of the containing hole 211 facing the positioning mechanism 10 is greater than the cross-sectional area of the other end of the containing hole 211 away from the positioning mechanism 10, and the structure of the sliding piece 221 is matched with the structure of the containing hole 211, so as to avoid the sliding piece 221 from falling out of the containing hole 211.

[0027] The accommodation holes 211 can be provided in three, four, five, etc., the number of accommodation holes 211 is greater than or equal to the number of accessories 300, the position of the accommodation hole 211 corresponds to the position of the accessory 300 on the workpiece 200. The material of the sliding piece 221 can adopt a metal material, such as aluminum alloy, titanium alloy, etc. The metal material of the sliding piece 221 has good wear resistance, which is beneficial to improve the service life of the pressure head assembly 22. And in the process of pressing, the metal material of the sliding piece 221 will not cause the accommodation hole 211 to be clamped due to deformation, which is beneficial to improve the pressing effect. In this embodiment, the surface roughness of the sliding piece 221 is Ra0.4μm~Ra1.6μm, and the surface of the sliding piece 221 is treated by hard anode, the hole wall surface of the accommodation hole 211 is smooth without burr, the roughness of the hole wall of the accommodation hole 211 is Ra0.4μm~Ra1.6μm, so that the sliding degree of the sliding piece 221 in the accommodation hole 211 can be improved, which is beneficial to improve the pressing effect. The flexible pressure head 222 adopts a material of excellent glue, which can ensure the pressing strength of the accessory 300, and can flexibly contact the accessory 300 or the workpiece 200, avoiding damage to the workpiece 200 or the accessory 300 due to rigid contact, and playing a certain protection role.

[0028] The pressing jig 100 provided by the embodiment of the application can support and position the workpiece 200 with the accessory 300 pasted thereon, and can ensure the accurate and fixed position of the workpiece 200 in the pressing process, thereby providing a basis for subsequent accurate pressing with the accessory 300. The pressing mechanism 20 is provided with a cover plate assembly 21 and a plurality of pressure head assemblies 22, the cover plate assembly 21 is matched with the positioning mechanism 10, and the plurality of pressure head assemblies 22 are one-to-one corresponding to the plurality of accessories 300. When the pressing mechanism 20 and the positioning mechanism 10 are matched, the flexible pressure head 222 in the pressure head assembly 22 can abut against the accessory 300 on the workpiece 200, and then press the workpiece 200 and the accessory 300, thereby improving the connection strength of the workpiece 200 and the accessory 300, and the flexible pressure head 222 can also avoid damage to the workpiece 200 or the accessory 300 due to rigid contact. The flexible pressure head 222 in the pressure head assembly 22 is connected with the cover plate assembly 21 through the sliding piece 221, which effectively prevents the flexible pressure head 222 from being clamped in the cover plate assembly 21 due to deformation in the pressing process, thereby ensuring the smoothness of the pressing process and the consistency and reliability of the pressing effect, and effectively improving the service life of the pressure head assembly 22.

[0029] In some embodiments, please refer to Figure 1 and Figure 2The cover plate assembly 21 comprises an upper cover plate 212 and a connecting plate 213 arranged on the side of the upper cover plate 212 facing the positioning mechanism 10, and a plurality of accommodating holes 211 are arranged on the connecting plate 213. The accommodating hole 211 comprises an accommodating section 2111 and a sliding section 2112 which are connected to each other. The accommodating section 2111 is arranged towards the upper cover plate 212, and the sliding section 2112 is arranged away from the upper cover plate 212. The cross-sectional area of the accommodating section 2111 is larger than that of the sliding section 2112, and a limiting surface 2113 is arranged between the accommodating section 2111 and the sliding section 2112. The upper cover plate 212 can be in a plate structure and can be used to be connected with an external driving device (not shown in the figure) to drive the pressing mechanism 20 to automatically operate by the external driving device. The connecting plate 213 can also be in a plate structure. By designing the upper cover plate 212 and the connecting plate 213 separately, it is convenient to process the accommodating holes 211 and to install the sliding members 221 and the flexible pressing heads 222. The longitudinal section of the accommodating hole 211 is substantially T-shaped. In order to improve the limiting stability of the accommodating hole 211 to the sliding member 221, two limiting surfaces 2113 can be arranged in each accommodating hole 211 and on the opposite sides of the sliding section 2112.

[0030] Each sliding member 221 comprises a limiting end 2211 and a connecting end 2212 which are arranged oppositely. The limiting end 2211 is arranged to slide in the accommodating section 2111, and the cross-sectional area of the limiting end 2211 is larger than that of the connecting end 2212. The limiting end 2211 can abut against the limiting surface 2113 to limit the sliding member 221 when the sliding member 221 moves away from the upper cover plate 212. The connecting end 2212 is arranged to slide in the sliding section 2112 and is used to connect the flexible pressing head 222. The longitudinal section of the sliding member 221 is substantially T-shaped, and the thickness of the limiting end 2211 is smaller than the depth of the accommodating section 2111 of the accommodating hole 211. In this way, the limiting end 2211 can slide in the accommodating section 2111.

[0031] In some embodiments, please refer to Figure 1 and Figure 2Each pressure head assembly 22 further comprises a plurality of first elastic members 223, each of which is arranged in the accommodation section 2111 and has two ends respectively abutting against the upper cover plate 212 and the side of the limiting end 2211 facing the upper cover plate 212. The first elastic member 223 is used to push the sliding member 221 away from the upper cover plate 212. The first elastic member 223 can be an elastic structural member such as a spring, and each pressure head assembly 22 can be provided with two, three, four or the like first elastic members 223. It can be understood that the sliding member 221 or the upper cover plate 212 can be provided with a groove for accommodating the first elastic member 223, so as to accommodate the first elastic member 223 when it is compressed and improve the stability of the first elastic member 223. When the cover plate assembly 21 is combined with the positioning mechanism 10 during the working of the compression jig 100, the flexible pressure head 222 starts to contact and compress the workpiece 200 and the auxiliary material 300, and the first elastic member 223 can effectively buffer the impact force generated in this contact moment, so as to avoid damage to the workpiece 200, the auxiliary material 300 and the pressure head assembly 22 itself due to rigid collision. At the same time, the first elastic member 223 can give the sliding member 221 an elastic force, and then give the flexible pressure head 222 through the sliding member 221, so that the flexible pressure head 222 compresses the auxiliary material 300 to the workpiece 200.

[0032] In some embodiments, referring to Figure 1 and Figure 2 , the length of the sliding member 221 along the extension direction of the accommodation hole 211 is greater than or equal to the thickness of the connecting plate 213, so that when the sliding member 221 abuts against the upper cover plate 212, the flexible pressure head 222 is still located outside the accommodation hole 211. In this way, the flexible pressure head 222 can be prevented from entering the accommodation hole 211, the flexible pressure head 222 can be prevented from rubbing against the connecting plate 213, the position accuracy of the sliding member 221 and the flexible pressure head 222 during use can be improved, and the service life of the flexible pressure head 222 can be prolonged.

[0033] In some embodiments, referring to Figure 1 and Figure 2 , each flexible pressure head 222 is provided with a profiling portion 2221 at the end away from the sliding member 221, and the structure of the profiling portion 2221 is adapted to the structure of the corresponding auxiliary material 300. It can be understood that different auxiliary materials 300 can have different shapes and different thicknesses. By providing the profiling portion 2221, the stability of the contact between the flexible pressure head 222 and the auxiliary material 300 can be improved, and the profiling portion 2221 with a corresponding thickness can be provided according to the thickness of the auxiliary material 300, so that when the limiting end 2211 of the sliding member 221 abuts against the limiting surface 2113, the profiling portion 2221 of the flexible pressure head 222 can compress the corresponding auxiliary material 300.

[0034] In some embodiments, referring to Figure 1 andFigure 2 The pressing mechanism 20 further comprises a pre-pressing piece 23 and a plurality of second elastic pieces 24. The pre-pressing piece 23 is slidingly arranged in one of the accommodating holes 211. The pre-pressing piece 23 comprises oppositely arranged limiting portions 231 and pre-pressing portions 232. The limiting portions 231 are slidingly arranged in the corresponding accommodating segments 2111. The cross-sectional area of the limiting portions 231 is greater than that of the pre-pressing portions 232. The limiting portions 231 can abut against the corresponding limiting faces 2113 to limit the pre-pressing piece 23 when the pre-pressing piece 23 moves away from the upper cover plate 212. The pre-pressing portions 232 are slidingly arranged in the sliding segments 2112. The length of the pre-pressing portions 232 is greater than the sum of the lengths of the connecting end 2212 and the flexible pressing head 222. The plurality of second elastic pieces 24 are arranged in the corresponding accommodating segments 2111. The two ends of each second elastic piece 24 respectively abut against the upper cover plate 212 and the side of the limiting portion 231 facing the upper cover plate 212. The second elastic pieces 24 are used to push the pre-pressing piece 23 to move away from the upper cover plate 212.

[0035] The longitudinal cross-section of the pre-pressing piece 23 is substantially T-shaped. The material of the pre-pressing piece 23 can be white plastic steel or the like. The second elastic pieces 24 can be elastic structural pieces such as springs. The second elastic pieces 24 can be four, nine or the like, and are uniformly distributed on the side of the limiting portion 231 facing the upper cover plate. In the embodiment, the pre-pressing piece 23 corresponds to the position on the workpiece 200 where the auxiliary material 300 is not arranged. In order to further improve the pre-pressing effect, a plurality of pre-pressing pieces 23 can be arranged, such as two or three. The positions of the plurality of pre-pressing pieces 23 can be set according to the positions of the workpiece 200 and the auxiliary material 300, without affecting the pressing of the auxiliary material 300 by the flexible pressing head 222.

[0036] By arranging the pre-pressing piece 23, the workpiece 200 can be abutted and pre-pressed in the early stage of the pressing process. Since the length of the pre-pressing portion 232 is greater than the sum of the lengths of the connecting end 2212 and the flexible pressing head 222, the pre-pressing portion 232 can first contact and slightly hold the workpiece 200, so that the workpiece 200 is preliminarily fixed before formal pressing, preventing relative displacement or misalignment during subsequent full pressing by the plurality of flexible pressing heads 222. The relative position accuracy of the workpiece 200 and the auxiliary material 300 during the entire pressing process is improved, thereby improving the quality stability and consistency of the final product.

[0037] In some embodiments, please refer to Figure 1 and Figure 2The positioning mechanism 10 comprises a positioning plate 11 and a plurality of positioning blocks 12. The positioning plate 11 is provided with a bearing part 111 for bearing the workpiece 200. The plurality of positioning blocks 12 are arranged around the bearing part 111 and are used for positioning the workpiece 200. The positioning plate 11 can be in a plate structure to provide stable support for the workpiece 200. The bearing part 111 can protrude from the body of the positioning plate 11. If the side of the workpiece 200 away from the auxiliary material 300 has a protrusion or is connected with other parts, the bearing part 111 can be provided with a corresponding avoiding slot to avoid these structures. Thus, when the bearing part 111 bears the workpiece 200, the main body part of the workpiece 200 is in a horizontal state, facilitating the pressing.

[0038] In some embodiments, referring to Figure 1 and Figure 2 The positioning plate 11 is provided with a plurality of guide holes 112 which are arranged at intervals from the bearing part 111. The cover plate assembly 21 further comprises a plurality of guide pieces 25 which are connected to the side of the connecting plate 213 facing the positioning plate 11 and correspond to the plurality of guide holes 112 one by one. The guide pieces 25 are used for inserting into the corresponding guide holes 112 to guide the cover plate assembly 21. The guide holes 112 can be two, three, four or the like and can be arranged on opposite sides or four sides of the bearing part 111. The guide pieces 25 can be in a columnar structure. The number and position of the guide pieces 25 are consistent with those of the guide holes 112. Thus, during the closing of the pressing mechanism 20 and the positioning mechanism 10, the cooperation of the guide pieces 25 and the guide holes 112 plays an accurate guiding role. The guide pieces 25 can stably slide along the direction of the guide holes 112, so that the cover plate assembly 21 always maintains the correct path and posture when approaching the positioning plate 11, effectively avoiding the problem of inaccurate alignment of the pressing head assembly 22 with the workpiece 200 and the auxiliary material 300 due to the deviation or inclination of the cover plate assembly 21. This ensures that the flexible pressing head 222 can be accurately aligned with the position of the auxiliary material 300 on the workpiece 200 every time the mold is closed, thereby ensuring the consistency and stability of the pressing quality and improving the qualification rate of the product.

[0039] In some embodiments, referring to Figure 1 and Figure 2The cover plate assembly 21 further comprises a plurality of limit members 26, each of which is connected to the connecting plate 213 on the side facing the positioning plate 11, and each of which is used to abut against the positioning plate 11 during clamping to limit the movement distance of the connecting plate 213 towards the positioning plate 11. The limit member 26 can be a block structure, and the number of limit members 26 can be four, six, eight, etc. It can be understood that the plurality of limit members 26 are connected with the connecting plate 213, and during clamping, the plurality of limit members 26 are arranged around the bearing part 111. During clamping, the limit member 26 is used to abut against the positioning plate 11, which can accurately limit the movement distance of the connecting plate 213 towards the positioning plate 11, prevent the cover plate assembly 21 from exerting excessive pressure on the workpiece 200 and the auxiliary material 300 due to excessive downward movement, and avoid problems such as deformation of the workpiece 200, damage or uneven compression of the auxiliary material 300 due to excessive pressure.

[0040] In some embodiments, referring to Figure 1 and Figure 2 The workpiece 200 is provided with a plurality of positioning holes 201; the positioning mechanism 10 further comprises a plurality of positioning pins 13, each of which is arranged on the bearing part 111 and corresponds to the plurality of positioning holes 201, and the positioning pin 13 is used to cooperate with the positioning hole 201 to position the workpiece 200. The positioning pin 13 can be a columnar structure, and the number and position of the positioning pin 13 correspond to the number and position of the positioning hole 201 on the workpiece 200. In this way, when placing the workpiece 200, the workpiece 200 can be preliminarily positioned by the plurality of positioning blocks 12, and then precisely positioned by inserting the positioning pin 13 into the corresponding positioning hole 201.

[0041] The working process of the compression jig 100 provided by the embodiments of the present application is as follows:

[0042] First, the workpiece 200 with the auxiliary material 300 pasted thereon is placed on the bearing part 111 of the positioning plate 11 of the positioning mechanism 10, and the workpiece 200 is preliminarily positioned by the plurality of positioning blocks 12, and then precisely positioned by inserting the positioning pin 13 into the corresponding positioning hole 201, so as to ensure that the position of the workpiece 200 in the plane is accurate and fixed.

[0043] Then, the compression mechanism 20 is covered on the positioning mechanism 10 to clamp, and during clamping, the guide 25 on the cover plate assembly 21 slides along the guide hole 112 of the positioning plate 11 to accurately guide the movement of the cover plate assembly 21 and keep it on the correct path and posture.

[0044] When the cover plate assembly 21 gradually approaches the positioning plate 11, the pre-pressing member 23 first contacts the workpiece 200, and under the action of the second elastic member 24, the workpiece 200 is pre-pressed to prevent displacement or misalignment of the workpiece 200 during subsequent compression.

[0045] As the cover plate assembly 21 continues to descend, the flexible pressing head 222 in each pressing head assembly 22 begins to contact the auxiliary material 300 on the workpiece 200, and under the action of the first elastic member 223, elastically presses the respective corresponding auxiliary material 300 until the limiting member 26 abuts against the positioning plate 11. The limiting member 26 limits the movement distance of the connecting plate 213 towards the positioning plate 11, prevents over-pressing, ensures that the stroke of each pressing operation is the same, and guarantees the consistency of the pressing quality.

[0046] Finally, after completing the pressing, the cover plate assembly 21 ascends under the action of the power, returns to the initial position, and prepares for the next pressing operation cycle.
