[0041] When producing the battery box of a watch, it is necessary to weld metal sheets to the outer walls of the four corners of the battery box. Since the welding points need to be on the inside of the battery box, the battery box and the metal sheets need to be placed together before welding. However, during welding, the battery box is not placed horizontally, and there is an angle between the plane where the battery box is located and the horizontal plane. The existing technology cannot fix the battery box and the metal sheet well, resulting in errors during welding and waste of materials. Therefore, the problem of poor welding caused by unstable fixation of the battery box and the metal sheet during the battery box welding process needs to be solved urgently.

[0042] Based on the above concepts and problems, the present invention proposes a fixing fixture 100 .

[0043] Please refer to Figures 1 to 10 As shown, in an embodiment of the present invention, a fixing fixture 100 is provided for pressing the metal sheet 6 against the top corner of the battery box 5 to be processed. The fixing fixture 100 includes a fixing mechanism 1, and the fixing mechanism 1 includes an upper cover 11 and a base 12. The battery box 5 to be processed and the metal sheet 6 are placed in the base 12, and the upper cover 11 is covered and fastened on the base 12 to press the battery box 5 to be processed against the base 12 to avoid displacement between the battery box 5 and the metal sheet 6 during welding.

[0044] The upper cover 11 includes an upper cover body 111 and a pressing assembly 112. The upper cover body 111 is provided with a light-transmitting processing hole, so that the welding laser can pass through the light-transmitting processing hole to weld the metal sheet 6 to the top corner of the battery box 5. The pressing assembly 112 is connected to the upper cover body 111 and exposed from the light-transmitting processing hole. The pressing assembly 112 is used to press the battery box 5 to be processed so that the battery box 5 and the metal sheet 6 are attached to facilitate welding.

[0045] The base 12 includes a base body 121 and a pressing member 122. The battery box 5 to be processed is placed in the base body 121. The pressing member 122 presses the metal sheet 6 against the top corner of the battery box 5. The base body 121 is fixedly connected with the upper cover body 111, and the base body 121 is formed with a processing space for accommodating the battery box 5 to be processed and the metal sheet 6. The processing space is connected with the light-transmitting processing hole. The pressing assembly 112 extends from the opening of the battery box 5 to be processed and abuts against the inner bottom wall of the battery box 5 to be processed. The pressing member 122 is located in the base body 121, and extends into the processing space to abut against the metal sheet 6, so as to abut the metal sheet 6 against the top corner of the battery box 5 to be processed.

[0046] By clamping and fixing the upper cover body 111 and the base body 121, the clamping assembly 112 presses the battery box 5 to be processed against the base body 121, and the pressing member 122 presses the metal sheet 6 to fit tightly with the top corners of the battery box 5. The four top corners of the battery box 5 are fixed with metal sheets 6. During welding, the welding laser passes through the light-transmitting processing hole to weld the metal sheet 6 to the battery box 5, and the welding point is inside the battery box 5. During the welding process, by changing the position of the entire fixing mechanism 1, the top corner of the battery box 5 to be welded can be aligned with the transmitting head of the welding laser, and the four top corners of the battery box 5 can be welded in sequence. No matter how the position of the fixing mechanism 1 changes, there will be no relative displacement between the battery box 5 and the metal sheet 6 located in the fixing mechanism 1, thereby improving the welding efficiency.

[0047] In some embodiments, please refer to Figures 4 to 6The upper cover body 111 includes a cover plate 1111 and a cover body 1112 that are connected to each other, and the cover plate 1111 is located above the cover body 1112. The cover plate 1111 and the cover body 1112 can be fixed by screw connection, or other achievable connection methods are all acceptable, without specific limitation. The cover plate 1111 and the cover body 1112 are both provided with light-transmitting processing holes, and the clamping assembly 112 abuts between the cover plate 1111 and the cover body 1112, and is exposed from the light-transmitting processing holes. An anti-slip member 11123 is provided at one end of the cover body 1112 away from the cover plate 1111, which is used to limit the clamping assembly 112 in the hollow space of the cover body 1112 to prevent the clamping assembly 112 from falling off from the lower end of the cover body 1112. The anti-slipping member 11123 is provided with a light-transmitting processing hole, and the pressing assembly 112 abuts against the upper surface of the anti-slipping member 11123 and is exposed from the light-transmitting processing hole of the anti-slipping member 11123 to abut against the battery box 5. The cover plate 1111 is connected to the end of the cover body 1112 away from the base 12, and the pressing assembly 112 is limited in the cover body 1112 to prevent the pressing assembly 112 from falling off from the upper end of the cover body 1112 when pressing the battery box 5.

[0048] Please refer again Figure 4 The clamping assembly 112 includes a movable member 1121 and a pressing member 1122 connected to each other. The movable member 1121 abuts between the cover plate 1111 and the cover body 1112. The pressing member 1122 extends from the opening of the battery box 5 to be processed and abuts against the inner bottom wall of the battery box 5 to be processed at one end away from the movable member 1121. The movable member 1121 abuts against the upper surface of the anti-slip member 11123. The movable member 1121 is arranged in a ring shape, and four strips connected end to end in sequence can be arranged to form a square ring shape matching the anti-slip member 11123. Four pressing members 1122 can be arranged, and the four pressing members 1122 are connected to one end of the four strips away from the anti-slip member 11123 in a one-to-one correspondence, and are connected to the middle position of the strips.

[0049] The pressing member 1122 includes a mounting plate, a pressure strip and a pressing plate connected in sequence. The mounting plate is connected to the middle position of the strip. The mounting plate can be connected and fixed to the strip by a screw, or other possible connection methods can be used, without specific limitation. The pressure strip can also be provided with a certain curvature to enhance the pressing effect of the pressure strip. The pressure strip passes through the middle hole of the movable member 1121, so that the pressing plate extends from the opening of the battery box 5 to be processed and abuts against the inner bottom wall of the battery box 5 to be processed. By pressing the battery box 5 to be processed by the pressing plate, the contact area with the battery box 5 to be processed can be increased to prevent damage to the battery box 5 to be processed during the pressing process.

[0050] Please refer again Figure 5, a protrusion 11111 is provided at one end of the cover plate 1111 close to the cover body 1112, and a groove 11211 is provided at one end of the movable member 1121 close to the cover plate 1111, and the groove 11211 is abutted against the protrusion 11111 through a spring. The spring is limited between the groove 11211 and the protrusion 11111, which can prevent the movable member 1121 from twisting or deflecting when the spring is active. Under the action of the spring elastic force, the movable member 1121 can hover in the cover body 1112, and the pressing member 1122 presses the battery box 5 to be processed against the base 12. When the pressing member 1122 presses the battery box 5 to be processed, the battery box 5 will generate a certain thrust on the pressing member 1122, and the spring is compressed and pressed between the groove 11211 and the protrusion 11111. The movable member 1121 is abutted against the cover plate 1111 by the spring, which can form a certain buffer to prevent the pressing member 1122 from causing damage to the battery box 5.

[0051] Please refer to Figure 5 and Figure 6 , the outer wall of the cover 1112 is provided with a plurality of snap fasteners 11121, and the plurality of snap fasteners 11121 are snapped to the base 12. Four snap fasteners 11121 can be provided on opposite sides of the cover 1112, and two snap fasteners 11121 are provided on each side, so that the cover 1112 is firmly snapped to the base 12. A long rod can be passed through the snap fasteners 11121 and connected to the cover 1112, and a hook is provided on the inner side wall of the snap fastener 11121 near one end of the base 12, and the snap fastener 11121 can move within a certain angle around the long rod, so that the cover 1112 is hooked to the base 12 through the hook, which is convenient for installation and removal. The outer wall of the fastener 11121 away from the base 12 is provided with anti-slip grooves to increase friction. When the cover body 1112 and the base 12 need to be separated, the anti-slip grooves can be pressed to separate the hook claw of the fastener 11121 from the base 12, effectively preventing the operator's sweaty hands from slipping when contacting the fastener 11121.

[0052] In some embodiments, please refer to Figure 7 and Figure 8The base body 121 includes a limit plate 1211 and a base body 1212 which are connected to each other, and the limit plate 1211 is located above the base body 1212; the limit plate 1211 is used to limit the outer edge of the opening of the battery box 5 to be processed, and the base 1212 is used to limit the metal sheet 6 at the top corner of the battery box 5 to be processed. Spaces for accommodating the battery box 5 to be processed and the metal sheet 6 are formed in the limit plate 1211 and the base body 1212. The snap-fitting member 11121 is snap-fitted to the base body 1212. The base body 1212 is provided with a mounting hole 12121 matching the top member 122, and the top member 122 is abutted against the inner wall of the mounting hole 12121 through a spring. The top member 122 can be set to a T-shape, or other achievable shapes, without specific limitation. The mounting hole 12121 matches the pressing member 122 , and the pressing member 122 is limited in the mounting hole 12121 , and ensures that the tip of the pressing member 122 along the movement direction can pass through the mounting hole 12121 and extend into the accommodating space of the seat body 1212 .

[0053] The metal sheet 6 includes two straight edges connected perpendicularly to each other. The battery box 5 has four vertices, and a total of four metal sheets 6 need to be welded. Therefore, eight tension members 122 can be provided, or any other achievable number can be provided, without specific limitation. The eight tension members 122 are grouped in twos, and divided into four groups. The two tension members 122 in each group abut against the two edges of a metal sheet 6, and the four groups of tension members 122 abut against four metal sheets 6. The spring located between the tension member 122 and the inner wall of the mounting hole 12121 provides the tension member 122 with a thrust along the direction of movement of the tension member 122. Two springs can be provided correspondingly for each tension member 122 to avoid uneven force on the tension member 122 during the tensioning process, which causes the tension member 122 to be skewed, resulting in the failure to properly tighten the metal sheet 6 to the vertices of the battery box 5 to be processed.

[0054] Under the action of the spring force, the tip of the pressing member 122 along the moving direction can abut against the metal sheet 6, and press the metal sheet 6 against the top corner of the battery box 5 to be processed. The seat body 1212 is also provided with an adjustment hole matching the mounting hole 12121. The setting direction of the adjustment hole is the same as the moving direction of the pressing member 122, and the number of the adjustment hole matches the spring in the mounting hole 12121, so as to adjust the spring in the mounting hole 12121 to prevent the pressing member 122 from abutting against the metal sheet 6 too loosely or too tightly.

[0055] Please refer to Figure 5 and Figure 7A limiting rod 12122 is provided at one end of the seat body 1212 close to the cover body 1112, and a limiting hole 11122 matching the limiting rod 12122 is provided at one end of the cover body 1112 close to the seat body 1212. The limiting rod 12122 passes through the limiting plate 1211 and is inserted into the limiting hole 11122. Four limiting rods 12122 can be provided, or any other achievable number is acceptable, without specific limitation. The setting directions of the four limiting rods 12122 are all perpendicular to the plane where the seat body 1212 is located, and are provided along the direction close to the cover body 1112, wherein two limiting rods 12122 are located inside the seat body 1212, and the other two limiting rods 12122 are respectively located on the side walls on opposite sides of the seat body 1212.

[0056] When the operator buckles the upper cover 11 onto the base 12, the limiting rods 12122 located on the side walls on the opposite sides of the base 1212 can intuitively instruct the operator to buckle the upper cover 11 onto the base 12, and the two limiting rods 12122 located in the base 1212 can further limit the upper cover 11. The limiting rods 12122 are inserted into the corresponding limiting holes 11122, so that the clamping assembly 112 can better press the battery box 5 to be processed into the base 1212, thereby avoiding crooked installation between the upper cover 11 and the base 12 and uneven force on the battery box 5.

[0057] Please refer to Figure 7 and Figure 8 , the side wall of the seat body 1212 is also provided with a clamping piece, the number of which is the same as the number of the snapping pieces 11121, and the snapping pieces are inclined, and the setting height of the snapping pieces gradually increases in the direction away from the upper cover 11. During installation, the base 12 is placed horizontally, the limiting hole 11121 of the upper cover 11 is aligned with the limiting rod 12122, and the upper cover 11 is placed vertically from top to bottom. The hook of the snapping piece 11121 slides from top to bottom along the outer wall of the snapping piece of the seat body 1212, and finally clamps on the lower surface of the snapping piece. When the upper cover 11 and the base 12 need to be separated, the anti-slip pattern on the outer wall of the snapping piece 11121 away from the base 12 is pressed, and the snapping piece 11121 rotates along the long rod to separate the hook from the clamping piece, and the upper cover 11 can be removed.

[0058] In some embodiments, please refer again to Figure 2 The fixing jig 100 further includes a supporting mechanism 2, which includes an angle adjustment component 21 and a connecting piece 22 connected to each other, and one end of the base 12 away from the upper cover 11 is connected to the angle adjustment component 21. The battery box 5 to be processed and the metal sheet 6 are fixed in the fixing mechanism 1, and then the fixing mechanism 1 is connected to the angle adjustment component 21. The angle adjustment component 21 can achieve any processing angle. The angle adjustment component 21 is set according to the operating standard and connected to the welding equipment through the connecting piece 22, so that the battery box 5 to be processed in the fixing mechanism 1 can be welded.

[0059] The angle adjustment assembly 21 includes a rotating member 211 and a flip member 212 connected to each other. The end of the base 12 away from the upper cover 11 is connected to the rotating member 211, and the end of the flip member 212 away from the rotating member 211 is connected to the connecting member 22. The rotating member 211 can achieve 360° rotation. The rotating member 211 is provided with an electromagnet and a positioning pin. The end of the base 12 away from the upper cover 11 is also provided with a positioning hole matching the positioning pin. During installation, the positioning pin is aligned with the positioning hole of the base 12 and inserted into the positioning hole. The electromagnet is energized to firmly absorb the base 12, thereby realizing the connection between the fixing mechanism 1 and the supporting mechanism 2. The flip member 212 can achieve a certain angle of flipping. The flip member 212 includes a flap 2121 and a fixed plate 2122. The flap 2121 is connected to the rotating member 211, and the fixed plate 2122 is connected to the connecting member 22. An arc slide 21221 is also provided on the fixed plate 2122. The flap 2121 is connected between the two fixed plates 2122 through a bearing and is limited in the arc slide 21221, so that the flap 2121 can drive the rotating part 211 to move along the arc slide 21221 to achieve flipping to adjust the height of the fixing mechanism 1.
