Specifically, in the present embodiment, the pushing member 15 can drive the pressing member 14 to perform a linear motion along a vertical direction to press the pen cap 203, so that the alignment is accurate and easy to control. The pen container 201 is vertically and straightly fixed on the mounting seat 13, the connecting end of the pen container 201 faces upward and protrudes from the top end of the mounting seat 13, after the pen cap 203 is aligned and arranged on the pen container 201, the pressing member 14 can rotate from the upper side of the pen container 201 to the position right above the pen cap 203 and can be abutted against the pen cap 203, however, in other embodiments, the pushing member 15 can drive the pressing member 14 to perform oblique line motion along the vertical direction, the pen container 201 can also be obliquely fixed on the mounting seat 13, the connecting end of the pen container 201 can also be arranged protruding from the side end of the mounting seat 13, and after the pen container 201 and the pen cap 203 are aligned, the pressing member 14 can also fix the pen container 201 and the pen cap 203 from the lateral direction.

Specifically, in the present application, the pen container 201 may be fixed first, so as to dispense glue on the connection end of the pen container 201, and then the cap 203 is placed on the connection end of the pen container 201 after dispensing, at this time, the pressing member 14 is located at an initial position substantially flush with or slightly lower than the top end of the cap 203, and the pressing member 14 is pushed to rotate to abut against the cap 203, so that the pen container 201 and the cap 203 may be kept in an initially aligned abutting state, so as to be further aligned and adjusted for lamination. Moreover, the pushing piece 15 can be used for pushing the pushing piece 14 or loosening the pushing piece 14, so that the pushing piece 14 can make linear movement away from the pen container 201 to release the pushing of the pen cap 203, or the pushing piece 14 can make linear movement close to the pen container 203 to reset, and therefore the pen cap 203 can be pushed.

Specifically, the mounting base 13 is substantially L-shaped, and the mounting base 13 includes a relatively horizontal base 131 and a support base 132 perpendicular to the base 131. The slot 13a is specifically disposed along the longitudinal direction of the supporting seat 132 and located on the left side opposite to the supporting seat 132, and the slot 13a may be directly opened on the supporting seat 132 or may be formed on a clamping box 16. The clamping box 16 is detachably arranged on the supporting seat 132, and then the clamping box 16 with the corresponding slot 13a can be selected according to the specification and the size of the pen container 201, so that the pen container 201 with different sizes can be fixed, and the adaptability of the jig is improved.

More specifically, the clamping case 16 includes a bottom case 161 that can be fixed to the support base 132 and a cover plate 162 that can be fastened to the bottom case 161, and the pen container 201 is fastened to a slot 13a arranged along the longitudinal direction of the bottom case 161, and the slot 13a is a U-shaped groove or a V-shaped groove. The cover plate 162 and the bottom case 161 may be completely separated, or one end may be pivoted with the bottom case 161, and the other end may be rotatably fastened with the bottom case 161, so that the pen container 201 may be effectively fixed by fastening the cover plate 162 and the bottom case 161, preventing the pen container 201 from being displaced during assembly or transfer, and facilitating assembly and disassembly of the pen container 201.

Further, in order to facilitate positioning of the pen cap 203 on the pen container 201, the positioning fixture 12 of the present invention is further provided with a vacuum suction pen 70, wherein three positioning columns 71 are equidistantly arranged around the suction nozzle in the circumferential direction of the suction end of the vacuum suction pen 70, and positioning holes 16a are arranged in one-to-one correspondence with the positioning columns 71 at the top end of the bottom box 161 or the top end of the supporting seat 132. When the vacuum suction pen 70 is manually operated and the adsorbed pen cap 203 is arranged at the connecting end of the pen container 201, the pen cap 203 and the pen container 201 can be effectively aligned through the positioning column 71 and the positioning hole 16a, so that the accuracy and the efficiency of alignment are improved. As shown in fig. 2, the vacuum pen 70 may be hung at an inlet and an outlet of the casing 102, thereby facilitating operation.

Referring to fig. 5 to 7, the positioning jig 12 further includes a linkage assembly 17 disposed on the mounting base 13, the linkage assembly 17 is disposed on the right side opposite to the supporting base 132, one end of the linkage assembly 17 is pivoted with the pressing member 14, and the other end of the linkage assembly 17 is fixedly connected, movably connected or rotatably connected with the pushing member 15.

Specifically, in the present embodiment, the linkage assembly 17 includes a switching shaft 171, a fixing member 172 and a limiting member 173, the fixing member 172 is fixedly disposed on the supporting seat 132 of the mounting seat 13, the switching shaft 171 is rotatably and movably sleeved in the fixing member 172, the upper end of the switching shaft 171 is pivotally connected to the pressing member 21, the lower end of the switching shaft 171 is rotatably connected to the pushing member 15, a spiral guide groove 17a is disposed on the switching shaft 171 along the circumferential direction thereof, one end of the limiting member 173 is fixed on the supporting seat 132 of the mounting seat 13, and the other end of the limiting member 173 is slidably clamped in the guide groove 17 a. When the pushing member 15 moves linearly on the supporting seat 132 along the vertical direction to push the adapting shaft 171, the adapting shaft 171 can rotate and move relative to the fixing member 172 under the action of the pushing force provided by the pushing member 15 and the tangential force provided by the limiting member 173 and limited by the guiding slot 17a, so as to drive the pressing member 14 to move linearly to release the pressing of the cap 203, and when the pushing member 15 moves reversely, the pressing member 14 can realize the pressing of the cap 203.

Preferably, the number of the fixing members 172 may be two, and the two fixing members 172 are disposed on the supporting seat 132 at intervals and sleeved at opposite ends of the adapting shaft 171, so that the adapting shaft 171 is more stable in movement. The fixing member 172 is preferably a bearing, but may be a bushing, so long as it is a member capable of rotatably and movably connecting with the rotating shaft, and is not limited thereto. Of course, in other embodiments, the lower end of the adapting shaft 171 may be fixedly connected with the pushing member 15, and then the pushing member 15 may move linearly along the vertical direction on the supporting seat 132 to drive the adapting shaft 171 to move linearly up and down, so as to realize the reciprocating motion of the pressing member 14. When the lower end of the switching shaft 171 is movably connected with the pushing member 15 through a cam structure, the switching shaft 171 can be effectively controlled to move up and down by the relative sliding between the switching shaft 171 and the pushing member 15.

Specifically, the guiding groove 17a includes a first straight groove 17a1, a second straight groove 17a2 on both sides, and an arc-shaped groove 17a3 connected between the first straight groove 17a1 and the second straight groove 17a2, the first straight groove 17a1 and the second straight groove 17a2 are arranged parallel to and spaced apart from each other along the axial direction of the adapting shaft 171, and the end portion of the limiting member 173 is inserted into the guiding groove 17a in a clearance fit manner.

When the end of the limiting member 173 slides in the arc-shaped groove 17a3, the switching shaft 171 is both rotatable and movable; when the end of the stopper 173 slides in the first straight groove 17a1 or the second straight groove 17a2, the rotation of the adapter shaft 171 is limited because the first straight groove 17a1 and the second straight groove 17a2 are both straight grooves, and the adapter shaft 171 can only move straight in the vertical direction. Moreover, the closed ends of the first straight groove 17a1 and the second straight groove 17a2 can also play a role in stopping the stop member 173 from moving continuously, so that the switching shaft 171 drives the pressing member 14 to be positioned at the set working position. As shown in fig. 6, the stopper 173 is located at the closed end of the second straight groove 17a2, and the switching shaft 171 is located at the upper limit position, so that the pressing member 14 is in a state of releasing the pressing state without pressing the pen cap 203. As shown in fig. 7, the stopper 173 is located at the closed end of the first straight groove 17a1, and the switching shaft 171 is located at the lower limit position, so that the pressing member 14 is in a pressing state of pressing the pen cap 203.

Referring to fig. 8 and 9, the linkage assembly 17 further includes a locking member 174 mounted on the mounting base 13, the adapter shaft 171 is provided with a locking portion 17b matched with the locking member 174, and the locking member 174 can move linearly along a radial direction of the adapter shaft 171 to be locked in the locking portion 17b or be disengaged from the locking portion 17b, so as to limit or allow the movement and rotation of the adapter shaft 171. The locking portion 17b may be a slot disposed on the lower sidewall of the adapter shaft 171, and of course, the locking portion 17b may also be an annular groove disposed along the circumferential direction of the lower sidewall of the adapter shaft 171, so as to simplify the structure and facilitate the locking with the locking member 174. Wherein the end of the locking member 174 is an arcuate end. Specifically, in the present embodiment, a positioning member 175 is fixed on the supporting seat 132, and the locking member 174 is telescopically sleeved with the positioning member 175 along the radial direction of the adapting shaft 171. Preferably, an elastic member 176 is connected between the locking member 174 and the positioning member 175, and the elastic member 176 constantly drives the locking member 174 to linearly move toward the direction of being engaged with the locking portion 17b, and the elastic member 176 is specifically a spring.

When the adapter shaft 171 moves linearly downward rotationally, the outer wall of the adapter shaft 171 abuts against the end of the locking member 174 to compress the elastic member 176, so that the locking member 174 contracts in the radial direction of the adapter shaft 171 to avoid, so that the adapter shaft 171 continues to move downward until the end of the limiting member 173 slides to the closed end of the first straight groove 17a1, and the locking portion 17b of the adapter shaft 171 just rotates to be opposite to the locking member 174, the locking member 174 is clamped in the locking portion 17b under the restoring force of the elastic member 176, so that the adapter shaft 171 is limited from both ends, and is not moved and rotated any more, and the abutting member 14 is kept in the abutting state with the pen cap 203. When the switching shaft 171 is driven by the pushing member 15 to rotationally and linearly move upwards, the locking member 174 has an arc-shaped clamping end, and the corresponding locking portion 17b also has a certain radian, so that the elastic member 176 is compressed under the action of the pushing force, and the locking member 174 can be separated from the clamping connection with the locking portion 17b until the switching shaft 171 moves to the end of the limiting member 173 and slides to the closed end of the second straight slot 17a2, the pushing member 14 releases the pushing pressure on the pen cap 203, and the locking member 174 also moves outwards to reset under the action of the restoring force of the elastic member 176.

Further, an elastic member (not shown) may be disposed between the adapter shaft 171 and the mounting base 13 or between the adapter shaft 171 and the fixing member 172, and the elastic member constantly drives the adapter shaft 171 to linearly move toward the direction of being engaged with the locking member 174. The elastic member is specifically a spring.

Referring to fig. 6 and 8, the pushing member 15 is disposed at an edge of the mounting seat 13, and specifically is slidably disposed on the linear rail 1321 of the supporting seat 132. The pushing member 15 includes an abutment portion 151 located right below the adapter shaft 171, and the pushing member 15 slides on the linear sliding rail 1321 to make the abutment portion 151 push the adapter shaft 171 from below the adapter shaft 171. Specifically, the contact surface of the adapter shaft 171 and the contact portion 151 is a plane, and the contact portion 151 has an arc end capable of being contacted with the adapter shaft 171, so that the contact portion 151 is contacted with the adapter shaft 171 only by the arc end, thereby effectively reducing the contact surface, providing a pushing force and reducing the friction force, and facilitating the rotation of the adapter shaft 171. In order to ensure that the pushing element 15 moves linearly in the vertical direction, the base 131 is further provided with a guide rod 1311, the guide rod 1311 is arranged along the vertical direction, and the pushing element 15 is arranged on the guide rod 1311 in a penetrating manner and can slide along the guide rod 1311, so that the stability of the linear movement of the pushing element 15 is further ensured. In order to facilitate pushing of the pushing member 15, the pushing member 15 further includes a pushing portion 152, where the pushing portion 152 is located at a side end of the pushing member 15 and beyond an edge of the mounting seat 13.
