Description

Technical Field

[0001] The invention belongs to the technical field of automation equipment, and in particular relates to a needle insertion testing mechanism used in a narrow space. Background Art

[0002] The design of touch buttons is usually simpler than traditional mechanical buttons. It does not have a complex mechanical structure and can be integrated into the display panel of the product, making the product look neater and more beautiful. Therefore, it is widely used in electronic devices such as mobile phones, smart home control systems, and car control systems, and can be seen everywhere in life. With the continuous advancement of science and technology, today's electronic products are also constantly innovating in technology. People's requirements for electronic consumer products are getting higher and higher, especially the sensitivity and accuracy of touch buttons. In order to ensure sufficient competitiveness, functional tests are often performed on touch buttons during production to ensure production yield and improve product quality and reputation. The precision test of touch buttons mainly involves contact pressure test, internal circuit conduction test, and metal shell conduction test.

[0003] At present, conventional electronic component testing mainly uses probes to contact and energize the components in the electronic composition, thereby testing the quality, performance and function of the electronic components. When testing touch buttons, since it is necessary to press the front of the touch button and use the probe to contact and energize the sensor element vertically set on the back of the touch button, the touch button is generally placed upright in the carrier of the test equipment. However, it is more difficult to stably fix the upright touch button in the test equipment so that the probe and the core sensor element can stably contact and energize. Summary of the invention

[0004] The purpose of the present invention is to provide a needle lowering testing mechanism applied to a narrow space to solve the technical problems described in the background technology.

[0005] The needle testing mechanism used in a narrow space includes a base, a carrier plate seat is installed on the base, the carrier plate seat is provided with a product slot for placing a touch button panel, a special-shaped sensor element is vertically protruded on the back of the touch button panel, the touch button panel is vertically placed in the product slot, a horizontal push cylinder is installed on the carrier plate seat, the horizontal push cylinder is transmission-connected with a horizontal movement seat, a product fixing block is provided on the horizontal movement seat, the horizontal push cylinder drives the horizontal movement seat to drive the product fixing block to lean against the product slot to push and fix the side of the touch button panel, and the product fixing block is provided with a probe with an elastic head, so that after the product fixing block leans against the product slot to touch the button panel, the probe contacts the sensor element and is energized.

[0006] According to the technical solution, the present invention can achieve the following beneficial effects: 1. After the touch key panel is placed in the product slot, the horizontal push cylinder drives the horizontal shift seat to drive the product fixing block into the product slot to push the side of the touch key panel, so as to clamp and fix the vertically placed touch key panel, so that the probe can stably contact and energize the sensor element on the back of the touch key panel; 2. Since the probe is provided with an elastic head, the probe can be in contact with a sensor element having an irregular boss shape.

[0007] In order to further optimize the above technical solution, it can be optionally combined with one or more of the following implementation methods without conflict.

[0008] In some embodiments, at least two sensor elements are arranged on the back of the touch key panel, the product fixing block is provided with a support spring, the support spring supports a cross bar that can float vertically up and down, the probe is provided on the cross bar, and when the cross-push cylinder drives the cross-movement seat to drive the product fixing block to lean against the product groove to push and fix the side of the touch key panel, the cross-movement seat synchronously drives the cross bar to extend between the two sensor elements on the back of the touch key panel, so as to realize that the probe can be driven to press down to the sensor element by pushing the cross bar; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. At least two sensor elements are arranged on the back of the touch button panel, and when the probe needs to contact with a wall surface of the sensor element close to another sensor element to be energized, a cross bar that can move synchronously is provided on the product fixing block, and at the same time, the probe is provided on the cross bar, so that when the cross-push cylinder drives the cross-movement seat to drive the product fixing block to push and fix the side of the touch button panel into the product groove, the cross bar simultaneously extends between the two sensor elements on the back of the touch button panel. Subsequently, the probe can be pressed down to the sensor element by pushing the cross bar to make the probe contact with a wall surface of the sensor element close to another sensor element to be energized.

[0009] 2. After the test is completed, stop pushing the crossbar, and the support spring can push the crossbar to move, so as to drive the probe to move away from the sensor element; 3. It is also possible to arrange crossbars in different positions to achieve contact with the sensor element in different directions.

[0010] In some embodiments, the carrier seat is equipped with a rocker, the middle part of the rocker is connected to the carrier seat bearing, one end of the rocker is provided with a sliding column that can slide on the cross bar, the base is equipped with a lifting cylinder, the lifting cylinder is transmission-connected with a push rod, and the push rod is connected to the other end of the rocker shaft, so that after the cross bar extends into between the two sensor elements on the back of the touch key panel, the lifting cylinder drives the push rod to pull the rocker to swing, and the rocker drives the sliding column to press down the cross bar to drive the probe to press down and contact the sensor element; According to the technical solution, the present invention can further achieve the following beneficial effects: 1. After the crossbar is extended into between the two sensor elements on the back of the touch key panel, the crossbar can be pressed down through a mechanical mechanism to drive the probe to press down and contact the sensor element; 2. Since the slide column can slide on the cross bar, the slide column used to press down the cross bar will not prevent the transverse seat from driving the cross bar to move.

[0011] In some embodiments, the carrier seat is installed with a positive magnet and a negative magnet, and the crossbar is installed with a passive magnet. When the crossbar is extended into between two sensor elements on the back of the touch key panel, the passive magnet is away from the negative magnet and is located above the positive magnet. At this time, the positive magnet drives the crossbar down by absorbing the passive magnet, so that the crossbar drives the probe to press down and contact the sensor element. When the crossbar moves out of between the two sensor elements on the back of the touch key panel, the passive magnet is away from the positive magnet and close to the negative magnet. At this time, the negative magnet repels the passive magnet to push the crossbar to gradually rise, and the probe also gradually moves away from the sensor element. According to the technical solution, the present invention can further achieve the following beneficial effects: 1. After the crossbar is extended into the space between the two sensor elements on the back of the touch key panel, since the passive magnet is away from the negative magnet and located above the positive magnet at this time, the positive magnet drives the crossbar down by absorbing the passive magnet, thereby automatically driving the crossbar to drive the probe to press down and contact the sensor element to energize; 2. When the positive magnet drives the crossbar down by attracting the passive magnet, the support spring can buffer and slow down the crossbar, thereby preventing the probe from causing excessive impact on the sensor element; 3. When the crossbar moves out from between the two sensor elements on the back of the touch key panel, the passive magnet is away from the positive magnet and close to the negative magnet, so the positive magnet's adsorption of the passive magnet is reduced. At this time, the elastic force of the supporting spring can push the crossbar to rise gradually, thereby avoiding damage caused by the crossbar resetting too quickly. 4. Through the setting of the negative magnet, when the crossbar moves out of the two sensor elements on the back of the touch key panel, the passive magnet moves away from the positive magnet and approaches the negative magnet. At this time, the negative magnet repels the passive magnet to push the crossbar to gradually rise, and the probe gradually moves away from the sensor element. Thus, the rising speed of the crossbar is controlled by the cooperation of the positive magnet and the negative magnet to prevent the crossbar from rising too fast and damaging the sensor element above it. 5. Due to the repulsive reaction of the compression magnet, the positive magnet and the negative magnet cooperate with each other, so that the reset and downward pressing stroke of the crossbar can be buffered and decelerated, so as to achieve gradual lifting and lowering at a slow speed; 6. By setting the negative magnet, the crossbar can be supported by the repulsive force of the negative magnet on the passive magnet, thereby eliminating the need for a support spring.

[0012] In some embodiments, the product fixing block is provided with a supporting block, and when the product fixing block is inserted into the product slot to push and fix the side of the touch key panel, the supporting block extends under the sensor element on the back of the touch key panel to support the sensor element; According to the technical solution, after the touch key panel is placed in the product slot, the touch key panel and the sensor element on the back thereof are further supported, so that the probe can more stably contact and energize the sensor element on the back of the touch key panel.

[0013] In some embodiments, the sensor element has a flexible flat cable extending outwardly, and the carrier base is installed with a cable support platform for supporting the flexible flat cable; According to the technical solution, when a flexible flat cable extends outward from the back of the sensor element or the touch button panel, after the touch button panel is placed in the product slot, the flexible flat cable can be supported, thereby reducing the risk of the flexible flat cable breaking.

[0014] In some embodiments, the carrier seat is equipped with a buffer spring that pushes the product fixing block into the product slot to clamp and fix the touch key panel; According to the technical solution, when the transverse pushing cylinder drives the transverse moving seat to drive the product fixing block into the product groove, the elastic force of the buffer spring can push the product fixing block to push and fix the side of the touch button panel, thereby avoiding damage to the touch button panel caused by excessive pushing pressure of the transverse pushing cylinder.

[0018] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail with reference to the accompanying drawings. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present invention.

[0019] like Figures 1 to 9 As shown, this specific embodiment provides a needle testing mechanism for use in a narrow space, which includes a base 1, on which a carrier plate 2 is installed, and the carrier plate 2 is provided with a product slot 21 for placing a touch button panel 6, and a special-shaped sensor element 61 is vertically protruded on the back of the touch button panel 6, and the touch button panel 6 is vertically placed in the product slot 21, and the carrier plate 2 is installed with a horizontal push cylinder 3, and the horizontal push cylinder 3 is transmission-connected with a horizontal movement seat 31, and a product fixing block 32 is provided on the horizontal movement seat 31, and the horizontal push cylinder 3 drives the horizontal movement seat 31 to drive the product fixing block 32 to lean against the product slot 21 to push and fix the side of the touch button panel 6, and the product fixing block 32 is provided with a probe 42 with an elastic head, so that after the product fixing block 32 leans against the product slot 21 to touch the touch button panel 6, the probe 42 contacts the sensor element 61 and is energized.

[0020] After the touch button panel 6 is placed in the product slot 21, the horizontal push cylinder 3 drives the horizontal displacement seat 31 to drive the product fixing block 32 to lean against the product slot 21 to push the side of the touch button panel 6, thereby clamping and fixing the upright touch button panel 6, so that the probe 42 can stably contact the sensor element 61 on the back of the touch button panel 6 and be energized; in addition, since the probe 42 is provided with an elastic head, the probe 42 can contact the sensor element 61 with an irregular boss shape.

[0021] In some embodiments, at least two sensor elements 61 are arranged on the back of the touch button panel 6, the product fixing block 32 is provided with a support spring 41, the support spring 41 supports a cross bar 4 that can float vertically up and down, and the probe 42 is provided on the cross bar 4. When the cross-push cylinder 3 drives the cross-movement seat 31 to drive the product fixing block 32 to push and fix the side of the touch button panel 6 into the product groove 21, the cross-movement seat 31 synchronously drives the cross bar 4 to extend between the two sensor elements 61 on the back of the touch button panel 6, so as to realize that the probe 42 can be pressed down to the sensor element 61 by pushing the cross bar 4.

[0022] At least two sensor elements 61 are arranged on the back of the touch button panel 6, and when the probe 42 needs to contact and energize a wall surface of the sensor element 61 close to another sensor element 61, a cross bar 4 that can move synchronously is provided on the product fixing block 32, and the probe 42 is provided on the cross bar 4, so that when the cross-pushing cylinder 3 drives the cross-moving seat 31 to drive the product fixing block 32 to push and fix the side of the touch button panel 6 into the product groove 21, the cross bar 4 simultaneously extends between the two sensor elements 61 on the back of the touch button panel 6, and then, the probe 42 can be pressed down to the sensor element 61 by pushing the cross bar 4 to make the probe 42 contact and energize a wall surface of the sensor element 61 close to another sensor element 61.

[0023] After the test is completed, by stopping pushing the cross bar 4, the support spring 41 can push the cross bar 4 to move, so as to drive the probe 42 to move away from the sensor element 61; in addition, by arranging the cross bars 4 in different positions, it is possible to achieve contact with the sensor element 61 in different directions.

[0024] In some embodiments, a rocker 5 is installed on the carrier seat 2, the middle part of the rocker 5 is connected to the bearing of the carrier seat 2, a sliding column 51 that can slide on the cross bar 4 is set at one end of the rocker 5, and a lifting cylinder 52 is installed on the base 1. The lifting cylinder 52 is transmission-connected with a push rod 53, and the push rod 53 is connected to the other end axis of the rocker 5. After the cross bar 4 extends between the two sensor elements 61 on the back of the touch button panel 6, the lifting cylinder 52 drives the push rod 53 to pull the rocker 5 to swing, and the rocker 5 drives the sliding column 51 to press down the cross bar 4 to drive the probe 42 to press down and contact the sensor element 61.

[0025] After the cross bar 4 extends into between the two sensor elements 61 on the back of the touch button panel 6, the cross bar 4 can be pressed down through a mechanical mechanism to drive the probe 42 to be pressed down and contact the sensor element 61; at the same time, since the sliding column 51 can slide on the cross bar 4, the sliding column 51 used to press down the cross bar 4 will not prevent the transverse seat 31 from driving the cross bar 4 to move.

[0026] In some embodiments, the carrier base 2 is installed with a positive magnet and a negative magnet, and the cross bar 4 is installed with a passive magnet. When the cross bar 4 extends into between the two sensor elements 61 on the back of the touch button panel 6, the passive magnet is away from the negative magnet and is located above the positive magnet. At this time, the positive magnet drives the cross bar 4 to descend by adsorbing the passive magnet, so that the cross bar 4 drives the probe 42 to press down and contact the sensor element 61. In the process of the cross bar 4 moving out of between the two sensor elements 61 on the back of the touch button panel 6, the passive magnet is away from the positive magnet and close to the top of the negative magnet. At this time, the negative magnet repels the passive magnet to push the cross bar 4 to gradually rise, and the probe 42 also gradually moves away from the sensor element 61.

[0027] After the cross bar 4 extends into between the two sensor elements 61 on the back of the touch button panel 6, since at this time the passive magnet is away from the negative magnet and is located above the positive magnet, the positive magnet drives the cross bar 4 to descend by absorbing the passive magnet, thereby automatically driving the cross bar 4 to drive the probe 42 to press down and contact the sensor element 61 to be energized; at the same time, when the positive magnet drives the cross bar 4 to descend by absorbing the passive magnet, the support spring 41 can buffer and decelerate the cross bar 4, thereby preventing the probe 42 from causing excessive impact on the sensor element 61.

[0028] When the cross bar 4 moves out from between the two sensor elements 61 on the back of the touch button panel 6, the passive magnet is away from the positive magnet and close to the negative magnet, so the adsorption of the positive magnet on the passive magnet is reduced. At this time, the elastic force of the support spring 41 can push the cross bar 4 to gradually rise, thereby avoiding damage caused by resetting the cross bar 4 too quickly.

[0029] By setting the negative magnet, when the cross bar 4 moves out from between the two sensor elements 61 on the back of the touch button panel 6, the passive magnet moves away from the positive magnet and approaches the negative magnet. At this time, the negative magnet repels the passive magnet to push the cross bar 4 to gradually rise, and the probe 42 also gradually moves away from the sensor element 61. In addition, since the repulsive reaction of the compressible magnet can be achieved, the positive magnet and the negative magnet cooperate with each other, so that the resetting and downward pressing stroke of the cross bar 4 can be buffered and decelerated, so as to achieve gradual lifting and lowering at a slow speed. At the same time, by setting the negative magnet, the cross bar 4 can be supported by the repulsive force of the negative magnet on the passive magnet, thereby eliminating the support spring 41.

[0030] In some embodiments, the product fixing block 32 is provided with a supporting block 33. When the product fixing block 32 is inserted into the product slot 21 to push and fix the side of the touch button panel 6, the supporting block 33 extends under the sensor element 61 on the back of the touch button panel 6 to support the sensor element 61.

[0031] After the touch key panel 6 is placed in the product slot 21 , the touch key panel 6 and the sensor element 61 on the back thereof are further supported, so that the probe 42 can more stably contact and energize the sensor element 61 on the back of the touch key panel 6 .

[0032] In some embodiments, a flexible flat cable extends outward from the sensor element 61 , and the carrier base 2 is installed with a cable support platform for supporting the flexible flat cable.

[0033] When a flexible flat cable extends outward from the back of the sensor element 61 or the touch button panel 6 , after the touch button panel 6 is placed in the product slot 21 , the flexible flat cable can be supported, thereby reducing the risk of the flexible flat cable being broken.

[0034] In some embodiments, the carrier seat 2 is installed with a buffer spring 34 for pushing the product fixing block 32 into the product slot 21 to clamp and fix the touch button panel 6.

[0035] When the transverse pushing cylinder 3 drives the transverse moving seat 31 to drive the product fixing block 32 to lean against the product groove 21, the elastic force of the buffer spring 34 can push the product fixing block 32 to push and fix the side of the touch button panel 6, thereby avoiding the excessive pushing force of the transverse pushing cylinder 3 and causing damage to the touch button panel 6.

[0036] In some embodiments, the carrier seat 2 is equipped with a buffer spring 34 that pushes the product fixing block 32 into the product slot 21 to clamp and fix the touch key panel 6; According to the technical solution, when the horizontal push cylinder 3 drives the horizontal displacement seat 31 to drive the product fixing block 32 to lean against the product groove 21, the elastic force of the buffer spring 34 can push the product fixing block 32 to push and fix the side of the touch button panel 6, thereby avoiding damage to the touch button panel 6 caused by excessive pushing pressure of the horizontal push cylinder 3.

[0037] In order to further illustrate the needle insertion testing mechanism for use in a narrow space described in this specific implementation manner, the following embodiments are listed.

[0038] Example 1 like Figures 1 to 9 As shown, this embodiment provides a needle-down test mechanism for use in a narrow space, which includes a base 1, on which a board carrier 2, a cable support platform, and a lifting cylinder 52 are installed. The narrow space bidirectional motion needle-down test mechanism is used to test a touch key panel 6, on the back of which at least two vertically protruding sensor elements 61 with special shapes are arranged, and one of the sensor elements 61 has a flexible cable extending outward.

[0039] The carrier 2 is provided with a product slot 21 for placing the touch key panel 6. The touch key panel 6 is placed vertically in the product slot 21. At this time, the cable support platform is used to support the soft cable. The carrier 2 is equipped with a horizontal push cylinder 3, which is connected to the horizontal shift seat 31.

[0040] The traverse seat 31 is provided with a product fixing block 32, and the product fixing block 32 is provided with a supporting block 33. The traverse cylinder 3 drives the traverse seat 31 to drive the product fixing block 32 to lean against the product slot 21 to push and fix the side of the touch key panel 6, and the supporting block 33 extends under the sensor element 61 on the back of the touch key panel 6 to support the sensor element 61. The carrier seat 2 is equipped with a buffer spring 34 that pushes the product fixing block 32 to lean against the product slot 21 to clamp and fix the touch key panel 6.

[0041] The product fixing block 32 is provided with a supporting spring 41, and the supporting spring 41 supports a cross bar 4 that can float vertically up and down. The cross bar 4 can float vertically up and down on the product fixing block 32 by utilizing the cooperation of the guide shaft and the bushing. A probe 42 with an elastic head is provided on the cross bar 4. When the transverse push cylinder 3 drives the transverse shift seat 31 to drive the product fixing block 32 to lean against the product groove 21 to push and fix the side of the touch button panel 6, the transverse shift seat 31 synchronously drives the cross bar 4 to extend between the two sensor elements 61 on the back of the touch button panel 6.

[0042] The plate carrier 2 is also equipped with a rocker 5, the middle part of which is connected to the plate carrier 2 bearing, and one end of the rocker 5 is provided with a slide column 51 that can slide on the cross bar 4. The lifting cylinder 52 is connected to the push rod 53, and the push rod 53 is connected to the other end of the rocker 5. After the cross bar 4 extends into the space between the two sensor elements 61 on the back of the touch key panel 6, the lifting cylinder 52 drives the push rod 53 to pull the rocker 5 to swing, and the rocker 5 drives the slide column 51 to press down the cross bar 4 to drive the probe 42 to press down and contact the sensor element 61 to energize. When the horizontal push cylinder 3 drives the horizontal displacement seat 31 to drive the product fixing block 32 to move out of the product slot 21 to stop pushing and fixing the touch key panel 6, the cross bar 4 moves out from between the two sensor elements 61 on the back of the touch key panel 6.

[0043] Before the cross bar 4 moves out from between the two sensor elements 61 on the back of the touch button panel 6, the lifting cylinder 52 drives the push rod 53 to swing the rocker 5 in the opposite direction, and the rocker 5 drives the slide column 51 to rise to stop pressing down on the cross bar 4. At this time, the elastic force of the support spring 41 pushes the cross bar 4 to reset and rise, so as to drive the probe 42 to move away from the sensor element 61. At the same time, the swinging speed of the driving push rod 53 is controlled by the lifting cylinder 52, so that the slide column 51 can limit the reset and rising speed of the cross bar 4, until the cross bar 4 is completely moved out from between the two sensor elements 61 on the back of the touch button panel 6, and then the cross bar 4 is completely lifted and reset to the initial position to avoid the cross bar 4 rising too fast and damaging the sensor element 61 above it and rubbing against the sensor element 61 above it.

[0044] Example 2 This embodiment provides a needle insertion test mechanism for use in a narrow space, which includes a base 1, on which a board carrier 2 and a flat cable support platform are installed. The narrow space bidirectional motion needle insertion test mechanism is used to test a touch key panel 6, on the back of which at least two vertically protruding sensor elements 61 with special shapes are arranged, and one of the sensor elements 61 has a flexible flat cable extending outward.

[0045] The carrier 2 is provided with a product slot 21 for placing the touch key panel 6. The touch key panel 6 is placed vertically in the product slot 21. At this time, the cable support platform is used to support the soft cable. The carrier 2 is equipped with a horizontal push cylinder 3, which is connected to the horizontal shift seat 31.

[0046] The traverse seat 31 is provided with a product fixing block 32, and the product fixing block 32 is provided with a supporting block 33. The traverse cylinder 3 drives the traverse seat 31 to drive the product fixing block 32 to lean against the product slot 21 to push and fix the side of the touch key panel 6, and the supporting block 33 extends under the sensor element 61 on the back of the touch key panel 6 to support the sensor element 61. The carrier seat 2 is equipped with a buffer spring 34 that pushes the product fixing block 32 to lean against the product slot 21 to clamp and fix the touch key panel 6.

[0047] The product fixing block 32 is provided with a supporting spring 41, and the supporting spring 41 supports a cross bar 4 that can float vertically up and down. The cross bar 4 can float vertically up and down on the product fixing block 32 by utilizing the cooperation of the guide shaft and the bushing. A probe 42 with an elastic head is provided on the cross bar 4. When the transverse push cylinder 3 drives the transverse shift seat 31 to drive the product fixing block 32 to lean against the product groove 21 to push and fix the side of the touch button panel 6, the transverse shift seat 31 synchronously drives the cross bar 4 to extend between the two sensor elements 61 on the back of the touch button panel 6.

[0048] In addition, the crossbar 4 is equipped with a passive magnet, and the carrier seat 2 is also equipped with a positive magnet and a negative magnet. When the crossbar 4 extends into the space between the two sensor elements 61 on the back of the touch key panel 6, the passive magnet is away from the negative magnet and is located above the positive magnet. At this time, the positive magnet drives the crossbar 4 to descend by absorbing the passive magnet, so as to drive the crossbar 4 to drive the probe 42 to press down and contact the sensor element 61 to be energized. When the horizontal push cylinder 3 drives the horizontal displacement seat 31 to drive the product fixing block 32 to move out of the product slot 21 to stop pushing and fixing the touch key panel 6, the crossbar 4 moves out of the space between the two sensor elements 61 on the back of the touch key panel 6. In this process, the passive magnet is away from the positive magnet and close to the negative magnet. At this time, the negative magnet will repel the passive magnet to push the crossbar 4 to gradually rise, and the probe 42 will also gradually move away from the sensor element 61.

The needle insertion testing mechanism for use in a narrow space according to claim 2, characterized in that: The plate carrier (2) is provided with a rocker (5), the middle part of which is connected to the bearing of the plate carrier (2), one end of which is provided with a slide column (51) which can slide on the cross bar (4), and the base (1) is provided with a lifting cylinder (52), which is transmission-connected with a push rod (53), and the push rod (53) is axially connected to the other end of the rocker (5), so that after the cross bar (4) extends between the two sensor elements (61) on the back of the touch key panel (6), the lifting cylinder (52) drives the push rod (53) to pull the rocker (5) to swing, and the rocker (5) drives the slide column (51) to press down the cross bar (4), driving the probe (42) to press down and contact with the sensor element (61).

4. The needle insertion testing mechanism for use in a narrow space according to claim 2, characterized in that: The carrier seat (2) is provided with a positive magnet and a negative magnet, and the cross bar (4) is provided with a passive magnet. When the cross bar (4) extends between the two sensor elements (61) on the back of the touch key panel (6), the passive magnet is away from the negative magnet and is located above the positive magnet. At this time, the positive magnet drives the cross bar (4) to descend by absorbing the passive magnet, so that the cross bar (4) drives the probe (42) to press down and contact the sensor element (61). When the cross bar (4) moves out of between the two sensor elements (61) on the back of the touch key panel (6), the passive magnet is away from the positive magnet and close to the negative magnet. At this time, the negative magnet repels the passive magnet to push the cross bar (4) to gradually rise, and the probe (42) also gradually moves away from the sensor element (61).

5. The needle insertion testing mechanism for use in a narrow space according to claim 2, characterized in that: The product fixing block (32) is provided with a supporting block (33). When the product fixing block (32) is inserted into the product slot (21) to push and fix the side of the touch key panel (6), the supporting block (33) extends under the sensor element (61) on the back of the touch key panel (6) to support the sensor element (61).

6. The needle insertion testing mechanism for use in a narrow space according to claim 5, characterized in that: The sensor element (61) has a flexible flat cable extending outwardly, and the carrier seat (2) is equipped with a cable support platform for supporting the flexible flat cable.

7. The needle insertion testing mechanism for use in a narrow space according to claim 1, characterized in that: The plate carrier (2) is provided with a buffer spring (34) for pushing the product fixing block (32) into the product slot (21) to clamp and fix the touch key panel (6).
