When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element at the same time.

[0039] In addition, the descriptions of "first", "second", etc. in this application are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0040] This application proposes a fixture, referring to Figures 1 to 4 The fixture includes: a base 10, one side of which is provided with a receiving groove 11 for accommodating and receiving the first workpiece 71; a clamping assembly 20, which is used to clamp the peripheral side of the first workpiece 71; a cover plate 30 can be detachably connected to the base 10, and is used to clamp the two opposite surfaces of the first workpiece 71 together with the base 10; an airtight assembly 40, including an air seat 41 and a supporting member 42 arranged on the cover plate 30, an air duct 46 is arranged in the air seat 41, and the air duct 46 is formed with an upper air hole and a lower air hole on the surface of the air seat 41, the lower air hole is sealed by the first workpiece 71, and the supporting member 42 is arranged in the lower air hole and is used to support the second workpiece 72.

[0041] In the embodiment of the present application, the first workpiece 71 can be a mobile phone back plate, and a mounting hole is provided in the area of ​​the back plate opposite to the mobile phone camera. The second workpiece 72 can be a decorative piece provided in the mounting hole, and the decorative piece is in the shape of a ring sleeve, and a transparent glass sheet is provided in the ring sleeve to seal one end of the ring sleeve. A step is provided on the outer periphery of the ring sleeve, and the end face of the step abuts against the annular area on the outer periphery of the mounting hole of the first workpiece 71 to play a limiting role, and the airtight component 40 is used to detect the airtightness between the annular areas abutting against each other. After the first workpiece 71 is loaded into the receiving groove 11, the clamping component 20 fixes the peripheral side of the first workpiece 71. The cover plate 30 is installed on the base 10 and clamps and fixes the first workpiece 71 with the base 10. A pressure block 32 is elastically provided on one side of the cover plate 30 facing the base 10, and the pressure block 32 is used to press the first workpiece 71. One side surface of the first workpiece 71 is supported by the base 10, and the other surface abuts against the air seat 41. At this time, the abutting member 42 is located in the lower air hole, and the mounting hole is also in the lower air hole. The peripheral area of ​​the lower air hole is in contact with the first workpiece 71, and the lower air hole is sealed by the first workpiece 71. The abutment 42 is arranged in the lower air hole and is used to abut the second workpiece 72, ensuring that the step surface of the second workpiece 72 is kept in contact with the first workpiece 71 when the first workpiece 71 is clamped. The external air nozzle can be sealed and docked with the upper air hole, and air can be injected or exhausted into the airway 46. The air pressure in the airway 46 is detected by a barometer to determine the fit state of the second workpiece 72 and the corresponding mounting hole on the first workpiece 71, thereby checking whether the air tightness between the two meets the standard. When the air is injected or exhausted in the airway 46 for a period of time to maintain pressure, if the internal air pressure can be maintained within the set range, it means that the air tightness does not meet the standard. If the internal air pressure cannot be maintained within the set range, it means that the air tightness does not meet the standard, and the first workpiece 71 and the second workpiece 72 need to be specifically tested to find defects. Therefore, the air tightness of the first workpiece 71 and the second workpiece 72 can be tested before the two are completely fixed, which can reduce the scrapping or rework of the workpieces.

[0042] It is worth noting that, since a mobile phone is generally provided with multiple cameras, multiple second workpieces 72 will be provided on the corresponding first workpiece 71, and the air tightness between each second workpiece 72 and the first workpiece 71 needs to be tested, so multiple air passages 46 can be provided to match one by one with different cameras to detect the air tightness of different mounting holes. Of course, multiple air passages 46 can be provided independently one by one, or each air passage 46 can be provided in communication. A first sealing ring 44 is provided on the lower end surface of the air seat 41, and each lower air hole is located in the first sealing ring 44. The first sealing ring 44 abuts against the surface of the first workpiece 71, thereby keeping the lower end of the air seat 41 sealed. In addition, the abutting member 42 is provided in the air passage 46 and can be rigidly connected to the air passage 46, but the rigid connection may cause certain damage to the first workpiece 71, such as the first workpiece 71 may be fractured due to the dimensional deviation of the first workpiece 71 and the second workpiece 72. Therefore, the abutting member 42 can be movably arranged in the airway 46, and a third elastic member 47 is arranged to abut against the abutting member 42. The third elastic member 47 can be a spring. The spring provides a certain downward pressure to keep the abutting member 42 and the second workpiece 72 in abutment, and also enables the abutting member 42 to have a certain activity space. The abutting member 42 is hollow so that the airway 46 is unobstructed. The abutting member 42 also includes a guide portion and a supporting portion. The supporting portion is in a ring-shaped sleeve to facilitate the abutment of the second workpiece 72, and the guide portion is square and slidably connected to the airway 46. The outer size of the guide portion is larger than the outer size of the supporting portion, so that a step surface for limiting can also be formed between the two. The airway 46 is arranged in a step hole shape, and the step surface of the step hole abuts against the step surface of the abutting member 42 to play a role in limiting. Correspondingly, the airtight component 40 also includes a fixed plate 43 arranged at the upper end of the air seat 41, and the fitting surface between the fixed plate 43 and the air seat 41 can also be sealed by setting a second sealing ring 45. At the same time, the setting of the fixing plate 43 can also prevent the abutting part from sliding out of the air hole on the air seat 41, and the other end of the spring abuts against the fixing plate 43. The fixing plate 43 is provided with an opening connected to the air passage 46, and the opening is used to dock with the air nozzle. Of course, the air seat 41 can also be elastically connected to the cover plate 30, so that when the air nozzle docks with the air seat 41, the pressure applied by the air nozzle on the air seat 41 is partially offset by the elastic force of the spring, thereby reducing the pressure directly applied by the air seat 41 on the first workpiece 71.

[0043] In some embodiments, reference Figure 1 and Figure 2The fixture further includes: a hook 12, which is arranged on the base 10; a buckle 31, which is slidably arranged on the cover plate 30; a first elastic member, one end of which is connected to the buckle 31 and the other end of which is connected to the cover plate 30; the hook 12 is adapted to the buckle 31, and the elastic force of the first elastic member causes the buckle 31 to engage with the hook 12. In this embodiment, the hook 12 can be arranged at the four corners of the base 10, and the buckle 31 can be slidably arranged at the four corners of the cover plate 30 and correspond to the hook 12 one by one. A guide slope is arranged at the end of the hook 12. The guide slope abuts against the inner edge of the buckle 31 to push the buckle 31 to move. Until the buckle 31 is inserted into the hook 12, the elastic force provided by the first elastic member causes the buckle 31 to abut against the hook 12, thereby locking the two. Such a setting allows the base 10 and the cover plate 30 to be detachably connected, and at the same time ensures that the two remain in a locked state when assembled together to clamp the first workpiece 71 and the second workpiece 72 inside. Even when the jig is being transferred, the first workpiece 71 and the second workpiece 72 inside will not move relative to each other, thereby ensuring accurate positioning of the first workpiece 71 and the second workpiece 72 .

[0044] In some embodiments, reference Figure 1 and Figure 2 The holding assembly 20 includes a limiter 21 disposed in the receiving groove 11, a clamping member 22 spaced apart from the limiter 21, the clamping member 22 is used to be slidably connected with the limiter 21, the clamping member 22 is slidably connected with the base 10, and the sliding direction is toward or away from the limiter 21, the clamping assembly 20 also includes a second elastic member elastically connected to the clamping member 22, and the elastic force of the second elastic member enables the clamping member 22 to clamp the first workpiece 71. In this embodiment, the clamping assembly 20 is used to clamp the peripheral side of the first workpiece 71, and the clamping member 22 is slidably disposed in a mounting seat 23 located at the edge of the receiving groove, and can be driven by a cylinder disposed on the base 10 to release or clamp the first workpiece 71. Of course, the clamping member 22 can also be driven by an external cylinder. The cylinder and the clamping member 22 are transmitted through a certain transmission member 24. As a result, the jig can be independently set so as to be transmitted between different workstations.

[0045] This application also proposes an assembly platform, referring to Figure 5 and Figure 6 The assembly platform includes a jig and a first base 50 for mounting the jig. In this embodiment, the first base 50 is used to place the jig. A positioning protrusion is provided on the first base 50 to facilitate positioning of the jig. Of course, a locking member 51 can also be provided on the first base 50 to lock the jig. The locking member 51 can be a locking cylinder with a certain rotation stroke of the push rod. A sensor 52 can also be provided on the first base 50 to sense the jig and / or the first workpiece 71.

[0046] In some embodiments, reference Figure 5The assembly platform further includes a first driving member 25 disposed on the first base 50, and a transmission member 24 slidably disposed on the first base 50; one end of the transmission member 24 is connected to the clamping member 22, and the other end is drivingly connected to the first driving member 25, and the first driving member 25 is used to drive the clamping member 22 to slide. In this embodiment, the first driving member 25 can be selected from a cylinder, and the first base 50 is provided with a first slider sliding along the X-axis direction and a second slider sliding along the Y-axis. Two first driving members 25 can be provided to respectively drive the first slider and the second slider to slide. The transmission member 24 can be optionally provided with a lever on the first slider and the second slider, and the free end of the lever passes through the base 10 and docks with the connecting hole 26 disposed on the clamping member 22. Thus, the lever can be driven by the first driving member 25 to move the clamping member 22 to release or lock the first workpiece 71 located in the receiving groove 11.

[0047] In some embodiments, reference Figure 6 The assembly platform also includes an adsorbent 60 and a detector. The adsorbent 60 is used to adsorb the first workpiece 71, and the detector is used to detect the pressure state of the adsorbent 60; one end of the adsorbent 60 is arranged on the first base 50, and a through hole 14 is also arranged at the bottom of the accommodating groove 11, and the other end of the adsorbent 60 is arranged in the through hole 14. The adsorbent 60 can be connected to an external vacuum pump to generate negative pressure to the first workpiece 71. When the first workpiece 71 is placed straight, it will be detected by the adsorption detector (pressure gauge) of the adsorbent 60 that the pressure inside the adsorbent 60 is maintained within the set range. When the first workpiece 71 is placed off-center and there is a certain overlap phenomenon, part of the adsorbent 60 fails to adsorb to the first workpiece 71, and the pressure value detected by the detector is outside the set range, and an alarm process can be performed later so that the first workpiece 71 can be re-placed.

In this embodiment, the flipping mechanism includes a clamping cylinder for clamping the fixture, and the side of the base 10 is provided with a positioning hole 15 for docking with the clamping cylinder. The flipping mechanism also includes a flipping cylinder connected to the clamping cylinder drive, and the flipping cylinder can flip the fixture 180 degrees so that the base 10 is facing the upper cover plate 30 and is set downward. The second base is correspondingly provided with a locking cylinder and a limiting protrusion to fix the cover plate 30 on the second base. The base 10 is also provided with an avoidance hole 13 corresponding to the second workpiece 72. The setting of the avoidance hole 13 exposes the first workpiece 71 to one side (inner side) of the battery. So that the end of the second workpiece 72 on this side can be fixed on the first workpiece 71 later. In this embodiment, the inner end of the second workpiece 72 can be fixed to the first workpiece 71 by a welding member, and the welding member can be an annular sheet, which is arranged on the outer periphery of the mounting hole.
