DETAILED DESCRIPTION

[0031] like Figures 1 to 3 As shown, a pressing device for control panel production is used to press a spring sheet 1 into the upwardly protruding blocks 3 on the left and right sides of the control panel 2. The spring sheet 1 is formed by bending and stamping a metal sheet, and a lug 4 is provided on the top of the spring sheet 1. The lug 4 has a non-circular groove structure. The bottom of the lug 4 is connected to a pair of main clamping arms 5 with openings facing downwards and a pair of auxiliary clamping arms 6 with openings facing downwards. The bottom of the auxiliary clamping arms 6 is higher than the bottom of the main clamping arms 5, and the opening width of the pair of auxiliary clamping arms 6 is smaller than the opening width of the pair of main clamping arms 5. The auxiliary clamping arms 6 are provided with clamp angles 7 bent toward each other. After the spring sheet is pressed into the clamping block 3, the pair of clamp angles 7 clamp the clamping block 3.

[0032] like Figure 4 As shown, the pressing device comprises a workbench 8, a positioning member 9, a feeding mechanism 10 and a pressing mechanism. The positioning member 9 is fixed on the workbench 8, and a positioning groove matching the shape of the control board 2 and used to position the control board is provided in the positioning member 9. The control board 2 is placed in the positioning groove before pressing.

[0033] The feeding mechanism 10 is used to convey the spring piece 1 to the top of the card block, such as Figure 5 , Figure 6 and Figure 8 As shown, the feeding mechanism 10 includes a support rod 11, a buffer member 12, a push block 13, an electric lead screw 14 and a push plate 15. The support rod 11 is horizontally arranged along the front and rear direction of the workbench 8, and its left and right ends are supported by support columns 16 on the table surface, respectively. The support column 16 is provided with a notch for avoiding the clamp angle 7, so that the spring piece can smoothly pass through the support column 16. Figure 7 As shown, the cross-sectional shape of the support rod 11 is adapted to the inner groove structure of the lug 4 of the spring piece, and a plurality of spring pieces 1 are connected in series on the support rod 11. The support rod 11 includes a loading end 17 and a unloading end 18 which are arranged oppositely, and pushes the spring piece toward the unloading end 18 during operation.

[0034] like Figure 5 and Figure 6 As shown, the cache component 12 is fixedly installed on the table top, and the cache component 12 is located between the support rod 11 and the push block 13. A cavity 19 that imitates the shape of the spring piece 1 is provided in the cache component 12. The cavity 19 is located on the horizontal extension line of the support rod 11 and the cavity 19 accommodates at least one spring piece. The cavity 19 fine-tunes and precisely positions the posture of the spring piece that is about to enter the push groove to prevent the spring piece 1 from shaking slightly and failing to smoothly enter the push groove of the push block 13.

[0035] The push block 13 is close to the buffer element 12 and is located directly above the card block 3. A push groove 20 that is shaped like the spring piece 1 is provided on the side of the push block 13 close to the buffer element 12. The initial position of the push groove 20 is located on the extension line of the cavity 16, so the spring piece 1 can be smoothly pushed from the cavity 19 into the push groove 20. A limiting portion 21 is provided on the side of the push block 13 away from the buffer element 12. The limiting portion 21 blocks and limits the spring piece 1 in the push groove 20 to prevent the spring piece 1 from sliding out horizontally from the push groove 20.

[0036] The pressing mechanism drives the push block 13, and the driving member 22 of the pressing mechanism drives the push block 13 downward to press the spring piece in the pushing groove 20 onto the clamping block 3. Specifically, the driving member 22 of the pressing mechanism is a cylinder or a hydraulic cylinder, and a transmission plate 23 is installed at the output end of the driving member 22. The push blocks 13 are respectively installed on the left and right sides of the transmission plate 23 with bolts, so that the two push blocks 13 can press the spring pieces on the left and right sides onto the clamping block 3 at the same time.

[0037] The electric lead screw 14 is installed on the table and parallel to the support rod 11. The electric lead screw 14 is driven by a stepper motor. A push plate 15 is installed on the slider of the electric lead screw 14. The push plate 15 is close to the auxiliary clamping arm 6 of the spring. The electric lead screw 14 intermittently drives the push plate 15 to push the spring 1 toward the lower material end 18. The stroke of each movement of the push plate 15 corresponds to the width of the spring 1.

[0038] Among them, an angle cylinder 24 is installed on the slider of the electric screw 14, and the rotating rod 25 of the angle cylinder 24 rotates in the vertical plane, and the rotating rod 25 is fixed to the push plate 15. When the push plate 15 moves to the side of the lower material end 18, the push plate 15 is driven by the angle cylinder 24 to rotate to the upright position, and then close to the spring piece. When the push plate 15 moves to the side of the upper material end 17, the push plate 15 is driven by the angle cylinder 24 to rotate to the side of the upper material end to be in a retracted position, and the angle between the retracted position and the horizontal plane is smaller than the angle between the upright position and the horizontal plane. Preferably, the push plate in the retracted position is in a horizontal state, so that the next batch of springs can be strung on the support rod 11 while the electric screw 14 resets the push plate 15. At this time, the push plate 15 can pass through the opening at the bottom of each spring on the support rod without contacting the spring.

[0039] like Figure 5 , Fig. 9 and Fig.10 As shown, a guide rail 26 extending in the vertical direction is provided on the side wall of the cache member 12 close to the push block 13, and a guide groove 27 cooperating with the guide rail 26 is correspondingly provided on the side wall of the push block 13. When the pressing mechanism presses down the push block 13, the guide groove 27 slides linearly along the guide rail 26 to prevent the push block 13 from shaking left and right, thereby ensuring that the push block 13 applies accurate clamping force to the spring piece 1.

[0040] like Fig. 9 As shown, the limiting portion 21 of the push block includes a retaining wall 28 and an avoidance gap 29. The retaining wall 28 protrudes inward from the push groove 20 to block the spring piece 1. The avoidance gap 29 extends vertically upward from the bottom of the retaining wall 28. The width of the avoidance gap 29 is slightly larger than the thickness of the block 3 of the control board. When the push block 13 presses the spring piece 1 into the block 3, the block 3 is inserted into the avoidance gap 29 to avoid interference between the push block 13 and the block 3.

[0041] An auxiliary pressing block 30 is installed in the middle of the transmission plate 23. The auxiliary pressing block 30 follows the transmission plate 23 downward to press the main part of the control plate 2, further reliably pressing the control plate 2 to prevent the control plate 2 from shaking and increasing the assembly error between it and the spring sheet 1. In order to improve the stability of the press-fitting, clamping cylinders can also be installed on the left and right sides of the positioning member to clamp the left and right side walls of the control plate.

[0042] The working process of this device is:

[0043] Place a control board 2 in the positioning groove of the positioning member 9, and string multiple spring pieces 1 on the support rod 11 in sequence; in the initial state, the pushing groove 20 of the pushing block 13 is aligned with the cavity 19 of the buffer member, and the spring piece can be reserved in the cavity 19;

[0044] Start the electric lead screw 14, drive the push plate 15 to push the spring piece 1 toward the lower material end 18 with a set stroke, push the spring piece on the far right in the cavity 19 into the push groove 20, and the spring piece is blocked by the limit portion 21 of the push block and cannot continue to move forward; this step is carried out simultaneously in the feeding mechanisms on the left and right sides;

[0045] The driving member 22 of the pressing mechanism is started to drive the push block 13 to push the spring piece in the pushing groove 20 downward until the auxiliary clamp arm 6 of the spring piece clamps the clamp block 3 of the control board, and the auxiliary pressing block 30 presses the main part of the control board 2; at the same time, the side wall of the push block 13 that fits the buffer member is used to block the next spring piece in the cavity 19;

[0046] Repeat the above feeding and pressing actions until all the spring pieces on the support rod 11 are fed into the cavity 19 of the buffer element;

[0047] The electric lead screw 14 drives the push plate 15 to reset to the upper material end 17 side, and the corner cylinder 24 drives the push plate 15 to flip to a horizontal state to avoid interference with the newly loaded spring pieces; during the reset process of the push plate 15, the next batch of spring pieces are loaded onto the support rod 11.

[0048] The control angle cylinder 24 turns the push plate 15 to the upright position, and the electric lead screw 14 drives the push plate 15 to move toward the lower material end 18 to start the next feeding cycle.
