Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Example 1

[0044] like Figures 1-3 As shown, a positioning fixture and an automatic assembly line include a frame 41, a turntable 42 mounted on the frame 41, a rotary power device 43 for driving the turntable 42 to rotate, and a plurality of assembly units arranged around the turntable 42. It further includes a positioning fixture 31 mounted on the turntable 42.

[0045] Specifically, the turntable 42 includes a movable disk 421 that is sleeved on the rotating power device 43 and can rotate with the rotating power device 43, and a fixed disk 422 that is fixedly installed on the top of the rotating device. That is, the fixed disk 422 is stationary on the rotating power device 43, and the movable disk 421 and the fixed disk 422 are concentric, while the fixed disk 422 is located above the movable disk 421, and the two are not in contact with each other.

[0046] The diameter of the fixed plate 422 is smaller than the diameter of the moving plate 421. The positioning clamp 31 is fixedly installed on the outer edge of the moving plate 421 by bolts. The fixed plate 422 is also provided with a first clamp adjustment device 32, a second clamp adjustment device 33 and a third clamp adjustment device 34 that cooperate with the positioning clamp 31.

[0047] Specifically, the assembling unit comprises a base assembling unit 11, a movable support assembling unit 12, a movable contact assembling unit 13, a spring assembling unit 14, an integral assembling unit 15, a discharging unit 16 and a clamp resetting unit 17, wherein the base assembling unit 11, the movable support assembling unit 12, the movable contact assembling unit 13 and the spring assembling unit 14 are respectively connected with a base feeding mechanism 21, a movable support feeding mechanism 22, a movable contact feeding mechanism 23 and a spring feeding mechanism 24. That is, the base feeding mechanism 21 is connected with the base assembling unit 11, and the base 51 is transported into the base assembling unit 11 through the base feeding mechanism 21; the movable support feeding mechanism 22 is connected with the movable support assembling unit 12, and the movable support 53 is transported into the movable support assembling unit 12 through the movable support feeding mechanism 22; the movable contact feeding mechanism 23 is connected with the movable contact assembling unit 13, and the movable contact 52 is transported into the movable contact assembling unit 13 through the movable contact feeding mechanism 23; the spring feeding mechanism 24 is connected with the spring assembling unit 14, and the spring 54 is transported into the movable contact assembling unit 13 through the spring feeding mechanism 24.

[0048] In the embodiment, the base feeding mechanism 21, the movable support feeding mechanism 22 and the spring feeding mechanism 24 are all vibration disc 421, and are transported in cooperation with a material channel and a direct vibration machine, and the feeding mechanism of the movable contact 52 is a cutting machine, which cuts a material belt with the movable contact 52 and then carries and feeds the material belt by a mechanical hand. The rotary power device 43 is a rotary motor or a rotary motor with a cam assembly for transmission.

[0049] It should be noted that the feeding modes of the base 51, the movable support 53, the spring 54 and the movable contact 52 are not limited, as long as these components can be transported to the corresponding assembling units.

[0050] Referring to Figures 15-21 The positioning clamp 31 will be described in detail.

[0051] As shown in Figure 21 , the switch comprises the base 51, the movable support 53, the movable contact 52 and the spring 54, and the movable support 53 and the movable contact 52 are connected at one end by the spring 54.

[0052] As shown in Figure 15 , the positioning clamp 31 comprises a clamping seat device 311, an adjusting mechanism A 312, an adjusting mechanism B 313 and a connecting plate 35, the clamping seat device 311 is used for clamping and fixing the base 51, and the adjusting mechanism A 312 and the adjusting mechanism B 313 are used for fixing the movable support 53 and the movable contact 52 so as to be adjusted and assembled by the integral assembling unit 15. The clamping seat device 311, the adjusting mechanism A 312 and the adjusting mechanism B 313 are all fixed on the connecting plate 35 by bolts.

[0053] Specifically, asFigure 16 As shown, the clamp seat device 311 includes a clamp seat body 3111, a clamping block 3112, and a locking block 3113 cooperating with the clamping block 3112. The clamp seat body 3111 is provided with a spring block one 3114 fixedly connected by bolts on the side close to the locking block 3113. The clamp seat body 3111 is provided with a reset spring A 3115 and a cavity A 3116 accommodating the reset spring A 3115. The clamping block 3112 is fixedly arranged in the clamp seat body 3111, and the locking block 3113 is movably arranged in the clamp seat body 3111, with one end abutting against the right side of the clamping block 3112. The left end of the clamping block 3112 is provided with a limiting block 3112', and the left end of the locking block 3113 is provided with a limiting portion 3113' cooperating with the clamping block 3112 for fixing the base 51, that is, when the locking block 3113 abuts against the clamping block 3112, the base 51 is fixed on the clamping block 3112 by cooperation of the limiting block 3112' and the limiting portion 3113'.

[0054] One end of the reset spring A 3115 abuts against the locking block 3113, and the other end abuts against the spring block one 3114. In order to prevent the spring from deforming and deviating, in this embodiment, the right side of the locking block 3113 and the spring block one 3114 are provided with a channel accommodating part of the reset spring A 3115. The locking block 3113 is further provided with a displacement groove 3113" cooperating with the base fitting unit 11.

[0055] As shown, Figure 17 The adjusting mechanism A 312 includes a first adjusting body 3121, a spring block two 3122 mounted on the left side of the first adjusting body 3121 by bolts, a top block 3123 movably arranged in the first adjusting body 3121, and a first adjusting block 3124. The top block 3123 can move left and right on the first adjusting body 3121, and the first adjusting block 3124 can move up and down on the first adjusting body 3121.

[0056] The top block 3123 is provided with an adjusting groove one 3125 through which the first adjusting block 3124 passes. The first adjusting block 3124 passes through the adjusting groove one 3125, and the first adjusting body 3121 is further provided with a cavity B 3126 having the same function as the cavity A 3116. The cavity B 3126 is provided with a reset spring B 3127, one end of which abuts against the end of the top block 3123, and the other end abuts against the spring block two 3122. It should be noted that the reset spring A 3115 and the reset spring B 3127 have the same function, and the recesses 3128 for adjusting the position of the top block 3123 are arranged on the left and right sides of the first adjusting block 3124.

[0057] The first adjusting block 3124 is located in the upper part of the left groove 3128, while the right groove 3128 is located in the middle or lower part of the first adjusting block 3124. That is, the left groove 3128 is higher than the right groove 3128, so that when the right groove 3128 is at the adjusting slot 3125, the top block 3123 can be adjusted left and right according to the state of the spring. It should be noted that in this embodiment, the return spring B3127 is a compression spring. Figure 17 In the middle, the return spring B3127 set in the cavity B3126 is in a compressed state, that is, the pressure block is in a contracted state.

[0058] like Figure 17 As shown, when the top block 3123 moves upward, the left side of the top block 3123 abuts against the first adjusting block 3124 and compresses the return spring B3127, causing the return spring B3127 to be in a compressed state, and the top block 3123 to be in a contracted state. When the first adjusting block 3124 is pressed downward, causing the groove 3128 on the left side to be in the adjusting groove 3125, the top block 3123 moves to the right and is pushed out under the action of the return spring B3127, thereby achieving the goal of controlling the extension and retraction state of the top block 3123 by controlling the position of the first adjusting block 3124.

[0059] like Figures 18-20 As shown, the adjustment mechanism B313 includes a fixed base 3131, a displacement base 3132, a cover plate 3133, a first movable block 3134 and a second movable block 3135 movably disposed within the displacement base 3132, and further includes a second adjustment block 3136 disposed through the fixed base 3131, the displacement base 3132 and the cover plate 3133. A third spring block 3138, which functions similarly to the first spring block 3114 and the second spring block 3122, is provided on both sides of the displacement base 3132 and the cover plate 3133. A return spring C3137 is provided between the first movable block 3134, the second movable block 3135 and the third spring block 3138. The first movable block 3134 is provided with a guide block 3134″ extending outward from the displacement base 3132, while the second movable block 3135 is provided with a clamping block 3135′ extending outward from the displacement base 3132. The clamping block 3135′ has an overall L-shaped structure.

[0060] Specifically, the longer end of the clamping block 3135' is inserted into the second movable block 3135, and the shorter end is arranged close to the guide block 3134". In the displacement seat 3132, a first stroke slot 3132' and a second stroke slot 3132" are arranged to facilitate the movement of the guide block 3134" and the clamping block 3135'. That is, the first movable block 3134 and the second movable block 3135 can move left and right in the displacement seat 3132, and the guide block 3134" and the clamping block 3135' can also move left and right in the first stroke slot 3132' and the second stroke slot 3132", thereby achieving the function of clamping and fixing an object.

[0061] Preferably, an auxiliary block 3134' is inserted into the guide block 3134" and the first movable block 3134, and the auxiliary block 3134' cooperates with the clamping block 3135' to limit the movement of the movable contact 52. The second adjusting block 3136 is provided with a first step 31361 on the left side and a second step 31362 and a third step 31363 on the right side, and the lower part of the first step 31361, the second step 31362, and the third step 31363 is provided with a transition slope 31366.

[0062] The height of the second step 31362 is less than the height of the third step 31363, and when the second movable block 3135 cooperates with the second step 31362, the first step 31361 is still above the first movable block 3134. When the second adjusting block 3136 moves downward, the second step 31362 cooperates with the second movable block 3135 to push it to the right, forcing the second movable block 3135 to move to the right. When the second adjusting block 3136 moves downward again, the first step 31361 and the third step 31363 cooperate with the first movable block 3134 and the second movable block 3135 respectively to move the first movable block 3134 and the second movable block 3135 to the left and right respectively. At this time, the adjusting mechanism B313 is in a relaxed state, and the left and right reset springs C3137 are in a compressed state.

[0063] The second adjusting block 3136 is provided with an inwardly recessed clamping groove 31365 below the first step 31361 and below the second step 31362. When the first movable block 3134 and the second movable block 3135 are at the clamping groove 31365, the first movable block 3134 and the second movable block 3135 are gathered to the center under the action of the reset spring C3137. At this time, the adjusting mechanism B313 is in a clamping state, that is, the distance between the auxiliary block 3134' and the clamping block 3135' is the smallest.

[0064] Below the clamping groove 31365, a fourth step 31364 is also provided, that is, two fourth steps 31364 with the same height are arranged on the left and right sides of the second adjusting block 3136.

[0065] Furthermore, the displacement seat 3132 is inclinedly mounted on the fixed seat 3131, and the adjustment mechanism B313 can move back and forth through the cooperation of the fixed seat 3131 and the displacement seat 3132.

[0066] Preferably, the first movable block 3134, the second movable block 3135, and the second adjusting block 3136 are further provided with an adjusting groove 3139 on the contact side. That is, the first movable block 3134 and the second movable block 3135 are guided and adjusted by the adjusting groove 3139 to prevent the second adjusting block 3136 from shifting during up and down movement, thereby affecting the clamping block 3135' and the auxiliary block 3134' in clamping the movable bracket 53. The first movable block 3134 and the second movable block 3135 have a U-shaped structure at one end of the adjusting groove 3139.

[0067] Reference Figures 4-14 Detailed descriptions of multiple assembly units are provided.

[0068] like Figures 4-5 As shown, the base 51 is transported to the base mounting unit 11 via the base feeding mechanism 21. The base mounting unit 11 is equipped with a mechanical claw 111 for transporting the base 51 and a displacement component 112 for driving the mechanical claw 111 to move up, down, left, and right. The mechanical claw 111 is also equipped with a mounting plate 113 that cooperates with the locking block 3113 of the clamping device 311 to move it to the right. The mounting plate 113 can be fixed at any position of the mechanical claw 111, such as on the plate body or gripper used to fix the mechanical claw 111. In this embodiment, the mounting plate 113 is fixed on the plate body of the mechanical claw 111. The mounting plate 113 is equipped with a protrusion 1131 that is inserted into the displacement groove 3113″ of the locking block 3113. That is, after the mechanical claw 111 grabs the base 51, it moves to the top of the positioning fixture 31 via the displacement component 112 on the base mounting unit 11. At this time, the positioning fixture 31 should be in an unloaded state.

[0069] When the mechanical claw 111 moves downward, the protrusion 1131 first inserts into the displacement groove 3113″, forcing the locking block 3113 to move to the right. When the base 51 is placed on the locking block 3112, the mechanical claw 111 moves upward, and the locking block 3113 is reset under the action of the return spring A3115, locking the base 51 for fixation.

[0070] The base 51, driven by the positioning clamp 31 and the rotating power device 43, moves towards the moving support mounting unit 12. For example... Figure 6 As shown, a first clamp adjustment device 32 is also provided at the moving bracket assembly unit 12 and fixedly mounted on the fixed plate 422. The first clamp adjustment device 32 mainly includes a telescopic power component 321 and a frame 322. The telescopic power component 321 is located above the first adjustment block 3124 of the positioning clamp 31.

[0071] The dynamic support fitting unit 12 is provided with a mechanical claw 121 rotating on the moving support 53 and a displacement assembly 122 driving the mechanical claw 121 to move up, down, left and right. When the dynamic support 53 is transported from the dynamic support feeding mechanism 22 to the dynamic support fitting unit 12, the dynamic support 53 is grabbed by the mechanical claw 121 and moved to the positioning clamp 31. When the dynamic support 53 is above the base 51, the first clamp adjusting device 32 drives the power telescopic piece to move downward to press the first adjusting block 3124 downward, so that the top block 3123 of the adjusting mechanism A 312 moves rightward to abut against the dynamic support 53 for fixation.

[0072] The positioning clamp 31 provided with the base 51 and the dynamic support 53 is moved to the dynamic contact piece fitting unit 13 under the driving of the rotary power device 43. Figures 7-8 As shown in the drawing, the dynamic contact piece fitting unit 13 is also provided with a second clamp adjusting device 33 fixedly arranged on the fixed disc 422. The second clamp adjusting device 33 mainly comprises a frame body 333, a telescopic power piece 331 driving the frame body 333 to move forward and backward, and a telescopic power piece 332 arranged on the frame body 333 and cooperating with the second adjusting block 3136.

[0073] The dynamic contact piece fitting unit 13 comprises a mechanical claw 131 specially used for carrying the dynamic contact piece 52 and a displacement assembly 132 driving the mechanical claw 131 to move up, down, left and right. When the dynamic contact piece 52 is carried from the dynamic contact piece feeding mechanism 23 to the dynamic contact piece fitting unit 13, the dynamic contact piece 52 is carried to the positioning clamp 31 provided with the base 51 and the dynamic support 53 by the mechanical claw 131. At this time, the fourth step 31364 of the second adjusting block 3136 abuts against the first movable block 3134 and the second movable block 3135. When the dynamic contact piece 52 is between the auxiliary block 3134' and the clamp block 3135', the second clamp adjusting device 33 drives the telescopic power piece 332 to press the second adjusting block 3136 downward, so that the clamping groove 31365 cooperates with the first movable block 3134 and the second movable block 3135 to clamp and fix the dynamic contact piece 52. Then, the positioning clamp 31 is moved to the spring fitting unit 14 by the rotary power device 43.
